steepest adhesion railway

Standard gauge track (4 feet 8-1/2 inches or 1435 millimeters) elevation of 10,015 feet, Cumbres Pass is the highest altitude operating Manchester Railway (1830). This mix of elastic distortion and local slipping is known as "creep" (not to be confused with the creep of materials under constant load). WebThe Schafberg Railway, in the Salzburg province, is Austrias steepest cog railway. The summit is famous for its giant statue of Christ the Redeemer and for its views over the city and beaches. Also, when the train encounters an unbanked turn, the wheelset displaces laterally slightly, so that the outer wheel tread speeds up linearly, and the inner wheel tread slows down, causing the train to turn the corner. It takes just over an hour to ascend Mt Washington's western flank to 1917 metres. the world. This allows the trains to operate on steep grades above 10%, which is the maximum for friction-based rail. The Lickey Incline is the steepest sustained main-line railway incline in Great Britain and is situated south of Birmingham, in England. by the Snaefell Mountain Railway on the Isle of Man. The system is characterized by two counterbalanced carriages permanently attached to opposite ends of a haulage cable, which is looped over a pulley at the upper end of the track. This diminishing "stick" area and increasing "slip" area supports a gradual increase in the traction or braking torque that can be sustained as the force at the wheel rim increases until the whole area is "slip". A larger number indicates higher or steeper degree of "tilt". See www.thecog.com. What is the highest railroad in the world? The world's steepest funicular railway has opened to the public in Switzerland. While traveling this means that electric locomotives may lose contact to the track-ground, causing the locomotive to create electromagnetic interference and currents through the couplers. At Alpnachstad, the Pilatus Railway connects with steamers on Lake Lucerne and with trains on the Brnigbahn line of Zentralbahn. Service was suspended from March 2008 until May 2009 for this work. The result is consistent with the kinematic result in that the critical speed depends inversely on the taper. The historical carriages are accessible for the disabled and have been gently modernised. 4.) How steep can a train climb? This line has been closed for over 50 years. Owned by the Norfolk Southern Railway as part of its W Line, Saluda Grade in Polk County, North Carolina, gains 606 feet (185 m) in elevation in less than three miles between Melros and Saluda. Residential areas were being created as well as merchants expanding their What is the steepest operating adhesion railway These tangential forces cause distortion in the region where they first come into contact, followed by a region of slippage. WebThe Katoomba Scenic Railway in Blue Mountains, New South Wales, Australia, has a 52-angle slope (128% maximum gradient). The inclusion of steep gradients on railways avoids the expensive engineering works required to produce more gentle gradients. Tramways and light railways often have steeper gradients than heavier railways. [7] That said, from the 1980s onwards, the Shinkansen engineers developed an effective taper of 1:16 by tapering the wheel with multiple arcs, so that the wheel could work effectively both at high speed as well as at sharper curves.[7]. WebLinz's Pstlingbergbahn, the steepest adhesion railway in Europe, creates a harmonious combination of nostalgia and modernity through its design. The Saluda Grade was created in the 1870s because the area surrounding Asheville and Saluda was expanding. The only public rack-and-pinion railway in the UK has operated for more than a century, and still runs original steam locomotives through the dramatic landscapes, at one point graced with a spectacular waterfall.

The line runs from Alpnachstad, on Lake Alpnach, to a terminus near the Esel summit of Pilatus at an elevation of 2,073m (6,801ft), which makes it the highest railway in the canton of Obwalden and the second highest in Central Switzerland after the Furka line. It runs from 1908 to 1974. Cass Scenic Railroad State Park Image Source Cass Scenic Railroad State Park is a State Park located in West Virginia, where d is the wheel gauge, r is the nominal wheel radius and k is the taper of the treads. WebAnswer (1 of 4): On any route, its the 1 in 5.5 (18.2%) on the 4.7 mile (7.25km) long Snowdon Mountain Railway in North Wales. Taking you from the mountain top town of Myrdal right down into the tiny town of Flm this train journey is one of the steepest in the world where most of the route is at a 5.5% gradient as it descends 863 meters into the valley below. However the maximum feasible gradient is limited by how much of a load the locomotive(s) can haul upwards. The behaviour of vehicles moving on adhesion railways is determined by the forces arising between two surfaces in contact. Such railways can use a number of different technologies to overcome the steepness of the grade. (elevation 9242 feet) is the highest freight railroad pass in the The Lickey Incline is the steepest sustained main-line railway incline in Great Britain and is situated south of Birmingham, in England. To help with braking on the descent, a non-load-bearing "brake rail" located between the running rails can be used, similar to the rail used in the Fell system, e.g. by the Snaefell Mountain Railway on the Isle of Man. grade in the world?

The line has ten stations, twenty tunnels and one bridge. What is the world's widest track gauge in use today? What is the highest operating freight railroad in The true situation is much more complicated, as the response of the vehicle suspension must be taken into account. While railways have a great ability to haul very heavy loads, this advantage is only significant when the tracks are fairly level. WebThe Cass is the steepest adhesion (non cable or cog) railway in the USA. The first is the inertia of the wheelsets and vehicle bodies, giving rise to forces proportional to acceleration; the second is the distortion of the wheel and track at the point of contact, giving rise to elastic forces. The heaviest trains require the highest friction and the heaviest locomotive. Standard gauge is used for most railroads The friction can vary a great deal, but it was known on early railways that sand helped, and it is still used today, even on locomotives with modern traction controls. In standstill, when the locomotive is parked, track circuits may detect an empty track because the locomotive is electrically isolated from the track.[17]. Since 2001, the steepest Balsam Mountain has seen many runaways.

Built as a rack railway, adhesion operation only by passenger railbuses, now only museum operation on part of the line. The Fell system was the first third-rail system for railways that were too steep to be worked by adhesion on the two running rails alone. The line was built by the Chemin de fer AigleLeysin. The 310-m-long (1,017-ft) funicular was originally built for mining purposes in 1878 but was converted into a recreational ride for tourists in 1945. There have been various solutions to hauling rail mounted vehicles up or down inclines. High adhesion locomotives control wheel creep to give maximum effort when starting and pulling a heavy train slowly. The C&HP was ancient and bizzarly engineered. At the top, you're rewarded with stunning lake, mountain and Dachstein Glacier views that extend over the Salzkammergut region in the heart of Austria's Alps. However, close examination of a typical railway wheel reveals that the tread is burnished but the flange is notthe flanges rarely make contact with the rail and, when they do, most of the contact is sliding. With a maximum grade of 11.6%, the Pstlingbergbahn is one of the steepest adhesion railways in the world. Operated from 1884 to 1909 when it was replaced by, The steepest standard gauge inclines used regularly by passenger trains by adhesion in Britain.

The 310-m-long (1,017-ft) funicular was originally built for mining purposes in 1878 but was converted into a recreational ride for tourists in 1945. Because of its steep gradient and picturesque nature, the Flam Line is today exclusively a tourist service and the third-most visited tourist attraction in Norway. When the train is in the centre of the track, the region of the wheels in contact with the rail traces out a circle which has the same diameter for both wheels. Friction-enhancing sand or an equivalent is needed. This was a branch line mainly serving limestone quarries and was latterly worked by small 0-6-0 saddle tanks - though I don't know whether that was by choice. WebLinz's Pstlingbergbahn, the steepest adhesion railway in Europe, creates a harmonious combination of nostalgia and modernity through its design. The inclusion of steep gradients on railways avoids the expensive engineering works required to produce more gentle gradients. The narrow gauge mining and Taplin, Michael; and Russell, Michael (2002). Often slope is calculated as a ratio of "rise" to "run", or as a fraction in which run is the horizontal distance and rise is the vertical distance. A funicular is a type of cable railway system that connects points along a railway track laid on a steep slope. Most rack railways are mountain railways, although a few are transit railways or tramways built to overcome a steep gradient in an urban environment. The maximum gradient on adhesion is 8% between Vetta Scorcola and Cologna stops. Replica trains are mostly used, but occasionally vintage steam trains from the late-nineteenth century make the 35-minute run through flower-studded meadows. Wilmington. The phenomenon of hunting was known by the end of the 19th century, although the cause was not fully understood until the 1920s and measures to eliminate it were not taken until the late 1960s. The Thamshavn Line was the first electric railway of Norway. UNESCO. In practice, the swaying is damped out below a critical speed, but is amplified by the forward motion of the train above the critical speed. steepest operating mainline grade in the USA was the 4.7% Saluda Built in 1882 at an Usui Pass, former Shin'etsu Main Line, Japan, Toden Arakawa Line (Tokyo Sakura Tram), Japan. In only 20 minutes, starting from Hauptplatz, its climbs Linz's local mountain. In practice, the minimum radius of turn is much greater than this, as contact between the wheel flanges and rail at high speed could cause significant damage to both. What is the steepest operating adhesion railroad grade in the USA? Some railway lines are so steep they require rack rails - toothed racks that the rails lock into using a cog or pinion. Braking when travelling downhill is also a limiting factor. The "factor of adhesion", being the weight on the driven wheels divided by the theoretical starting tractive effort, was generally designed to be a value of 4 or slightly higher, reflecting a typical wheel-rail friction coefficient of 0.25. including the Stockton & Darlington Railway (1825) and Liverpool & The worlds steepest adhesion railway grade is a 13.8% grade found on the tram network of LIsbon, Portugal. WebThe Bernina line is one of the highest alpine crossings in Europe and one of the steepest adhesion railway lines in the world.

This may appear trivially simple from a superficial glance but it becomes extremely complex when studied to the depth necessary to predict useful results. Balsam Mountain, home of highest railroad station east of the Rockies; average grade about 4.0%, max 4.5%. High-speed railways commonly allow 2.5% to 4% because the trains must be strong and have many wheels with power to reach very high speeds. For very high speed, the minimum adhesion limit again appears appropriate, implying a radius of turn of about 13km. It links Rheineck station, in the municipality of Rheineck and the canton of St Gallen, with the village and health resort of Walzenhausen, in the canton of Appenzell Ausserrhoden. A steep grade railway is a railway that ascends and descends a slope that has a steep grade. WebThe adhesion railway relies on a combination of friction and weight to start a train. Rails and railway wheels are much stiffer than pneumatic tyres and tarmac but the same distortion takes place at the region of contact. If wheelsets are rigidly coupled together, this motion is restricted, so that coupling the wheels would be expected to introduce sliding, resulting in increased rolling losses. Grades of 5% are not uncommon on them. Adhesion is caused by friction, with maximum tangential force produced by a driving wheel before slipping given by: Usually the force needed to start sliding is greater than that needed to continue sliding. The steepest adhesion worked grade in the UK was Hopton Incline on the former Cromford and High Peak Railway, at 1 in 14 (7.14%). On this Wikipedia the language links are at the top of the page across from the article title. 16,640 feet above sea level at Tanggula Pass, China. There are steeper grades on at least one other tram system, that of Lisbon, but the Pstlingbergbahn is still among the world's steepest adhesion railways and has the steepest grade of any in Austria. WebMetros and pure commuter railways often also allow steeper gradients, over 4%, for the same reason.

Standard gauge track (4 feet 8-1/2 inches or 1435 millimeters) elevation of 10,015 feet, Cumbres Pass is the highest altitude operating Manchester Railway (1830). This mix of elastic distortion and local slipping is known as "creep" (not to be confused with the creep of materials under constant load). WebThe Schafberg Railway, in the Salzburg province, is Austrias steepest cog railway. The summit is famous for its giant statue of Christ the Redeemer and for its views over the city and beaches. Also, when the train encounters an unbanked turn, the wheelset displaces laterally slightly, so that the outer wheel tread speeds up linearly, and the inner wheel tread slows down, causing the train to turn the corner. It takes just over an hour to ascend Mt Washington's western flank to 1917 metres. the world. This allows the trains to operate on steep grades above 10%, which is the maximum for friction-based rail. The Lickey Incline is the steepest sustained main-line railway incline in Great Britain and is situated south of Birmingham, in England. by the Snaefell Mountain Railway on the Isle of Man. The system is characterized by two counterbalanced carriages permanently attached to opposite ends of a haulage cable, which is looped over a pulley at the upper end of the track. This diminishing "stick" area and increasing "slip" area supports a gradual increase in the traction or braking torque that can be sustained as the force at the wheel rim increases until the whole area is "slip". A larger number indicates higher or steeper degree of "tilt". See www.thecog.com. What is the highest railroad in the world? The world's steepest funicular railway has opened to the public in Switzerland. While traveling this means that electric locomotives may lose contact to the track-ground, causing the locomotive to create electromagnetic interference and currents through the couplers. At Alpnachstad, the Pilatus Railway connects with steamers on Lake Lucerne and with trains on the Brnigbahn line of Zentralbahn. Service was suspended from March 2008 until May 2009 for this work. The result is consistent with the kinematic result in that the critical speed depends inversely on the taper. The historical carriages are accessible for the disabled and have been gently modernised. 4.) How steep can a train climb? This line has been closed for over 50 years. Owned by the Norfolk Southern Railway as part of its W Line, Saluda Grade in Polk County, North Carolina, gains 606 feet (185 m) in elevation in less than three miles between Melros and Saluda. Residential areas were being created as well as merchants expanding their What is the steepest operating adhesion railway These tangential forces cause distortion in the region where they first come into contact, followed by a region of slippage. WebThe Katoomba Scenic Railway in Blue Mountains, New South Wales, Australia, has a 52-angle slope (128% maximum gradient). The inclusion of steep gradients on railways avoids the expensive engineering works required to produce more gentle gradients. Tramways and light railways often have steeper gradients than heavier railways. [7] That said, from the 1980s onwards, the Shinkansen engineers developed an effective taper of 1:16 by tapering the wheel with multiple arcs, so that the wheel could work effectively both at high speed as well as at sharper curves.[7]. WebLinz's Pstlingbergbahn, the steepest adhesion railway in Europe, creates a harmonious combination of nostalgia and modernity through its design. The Saluda Grade was created in the 1870s because the area surrounding Asheville and Saluda was expanding. The only public rack-and-pinion railway in the UK has operated for more than a century, and still runs original steam locomotives through the dramatic landscapes, at one point graced with a spectacular waterfall.

More railroad records: Early Railroads, Locomotives, Bridges & Tunnels, Hillclimbing is a problem faced by railway systems when a load must be carried up an incline. The friction can vary a great deal, but it was known on early railways that sand helped, and it is still used today, even on locomotives with modern traction controls. There have been various solutions to hauling rail mounted vehicles up or down inclines. Causewayend incline, Slamannan Railway, Scotland, CologneFrankfurt high-speed rail line, Germany, Cumbres and Toltec Scenic Railroad, Colorado/New Mexico, United States, Durango and Silverton Narrow Gauge Railroad, Colorado, United States, Fujikyuko Line, Fuji Kyuko Railway, Japan. The line runs from Alpnachstad, on Lake Alpnach, to a terminus near the Esel summit of Pilatus at an elevation of 2,073m (6,801ft), which makes it the highest railway in the canton of Obwalden and the second highest in Central Switzerland after the Furka line. It runs from 1908 to 1974. Cass Scenic Railroad State Park Image Source Cass Scenic Railroad State Park is a State Park located in West Virginia, where d is the wheel gauge, r is the nominal wheel radius and k is the taper of the treads. WebAnswer (1 of 4): On any route, its the 1 in 5.5 (18.2%) on the 4.7 mile (7.25km) long Snowdon Mountain Railway in North Wales. Taking you from the mountain top town of Myrdal right down into the tiny town of Flm this train journey is one of the steepest in the world where most of the route is at a 5.5% gradient as it descends 863 meters into the valley below. However the maximum feasible gradient is limited by how much of a load the locomotive(s) can haul upwards. The behaviour of vehicles moving on adhesion railways is determined by the forces arising between two surfaces in contact. Such railways can use a number of different technologies to overcome the steepness of the grade. (elevation 9242 feet) is the highest freight railroad pass in the The Lickey Incline is the steepest sustained main-line railway incline in Great Britain and is situated south of Birmingham, in England. To help with braking on the descent, a non-load-bearing "brake rail" located between the running rails can be used, similar to the rail used in the Fell system, e.g. by the Snaefell Mountain Railway on the Isle of Man. grade in the world?

The worlds steepest adhesion railway grade is a 13.8% grade found on the tram network of LIsbon, Portugal. The Merthyr Tramroad was a 9.75 miles (15.69km) long line that opened in 1802, connecting the private lines belonging to the Dowlais and Penydarren Ironworks with the Glamorganshire Canal at Abercynon, also serving the Plymouth Ironworks along the way. High-speed railways commonly allow 2.5% to 4% because the trains must be strong and have many wheels with power to reach very high speeds. Metros and pure commuter railways often also allow steeper gradients, over 4%, for the same reason. How are model railroad grades calculated? The train's old wooden carriages feature in many a backdrop of Japanese movies set in pre-war days. The list of its authors can be seen in its historicaland/or the page Edithistory:List of steepest gradients on adhesion railways.

Properly dried sand can be dropped onto the rail to improve traction under slippery conditions. was abandoned in 1918. Regular passenger service withdrawn 6 September 1954 and since closed completely. The kinematic description of the motion of tapered treads on the two rails is insufficient to describe hunting well enough to predict the critical speed. 1 in 17.1 (5.88%) Docklands Light Railway, London, England: On the ramp from the original London and Blackwall Railway viaduct to the tunnel leading to Bank. All records listed on our website are current and up-to-date. The summit walk around The Peak on a circuit via Harlech and Lugard Roads is a delight, and has spectacular urban outlooks. The Saluda Grade was created in the 1870s because the area surrounding Asheville and Saluda was expanding. 4.) Regular passenger service withdrawn 6 September 1954 and since closed completely. It is present in a single wheelset and will accommodate the slight kinematic incompatibility introduced by coupling wheelsets together, without causing gross slippage, as was once feared. The longest straight track in the USA is 78.9 miles on CSX A locomotive with a factor of adhesion much lower than 4 would be highly prone to wheelslip, although some 3-cylinder locomotives, such as the SR V Schools class, operated with a factor of adhesion below 4 because the traction force at the wheel rim do not fluctuate as much. How steep can a train climb? is located on the former Seaboard Air Line route linking Hamlet and Tramways and light railways often have steeper gradients than heavier railways. Albula Railway Museum. When a wheel rolls freely along the rail the contact patch is in what is known as a "stick" condition. WebList of steepest gradients on adhesion railways The inclusion of steep gradientson railways avoids the expensive engineering works required to produce more gentle gradients.

Saluda Grade is the steepest standard-gauge mainline railway grade in the United States. To help with braking on the descent, a non-load-bearing "brake rail" located between the running rails can be used, similar to the rail used in the Fell system, e.g. The Pstlingbergbahn is a narrow-gauge electric railway, or "mountain tramway", in Linz, Austria. The line has ten stations, twenty tunnels and one bridge. What is the world's widest track gauge in use today? What is the highest operating freight railroad in The true situation is much more complicated, as the response of the vehicle suspension must be taken into account. While railways have a great ability to haul very heavy loads, this advantage is only significant when the tracks are fairly level. WebThe Cass is the steepest adhesion (non cable or cog) railway in the USA. The first is the inertia of the wheelsets and vehicle bodies, giving rise to forces proportional to acceleration; the second is the distortion of the wheel and track at the point of contact, giving rise to elastic forces. The heaviest trains require the highest friction and the heaviest locomotive. Standard gauge is used for most railroads The friction can vary a great deal, but it was known on early railways that sand helped, and it is still used today, even on locomotives with modern traction controls. In standstill, when the locomotive is parked, track circuits may detect an empty track because the locomotive is electrically isolated from the track.[17]. Since 2001, the steepest Balsam Mountain has seen many runaways.

Built as a rack railway, adhesion operation only by passenger railbuses, now only museum operation on part of the line. The Fell system was the first third-rail system for railways that were too steep to be worked by adhesion on the two running rails alone. The line was built by the Chemin de fer AigleLeysin. The 310-m-long (1,017-ft) funicular was originally built for mining purposes in 1878 but was converted into a recreational ride for tourists in 1945. There have been various solutions to hauling rail mounted vehicles up or down inclines. High adhesion locomotives control wheel creep to give maximum effort when starting and pulling a heavy train slowly. The C&HP was ancient and bizzarly engineered. At the top, you're rewarded with stunning lake, mountain and Dachstein Glacier views that extend over the Salzkammergut region in the heart of Austria's Alps. However, close examination of a typical railway wheel reveals that the tread is burnished but the flange is notthe flanges rarely make contact with the rail and, when they do, most of the contact is sliding. With a maximum grade of 11.6%, the Pstlingbergbahn is one of the steepest adhesion railways in the world. Operated from 1884 to 1909 when it was replaced by, The steepest standard gauge inclines used regularly by passenger trains by adhesion in Britain. Locomotives and streetcars/trams use sand to improve traction when driving wheels start to slip. Braking when travelling downhill is also a limiting factor. The straight worldwide. The 310-m-long (1,017-ft) funicular was originally built for mining purposes in 1878 but was converted into a recreational ride for tourists in 1945. Because of its steep gradient and picturesque nature, the Flam Line is today exclusively a tourist service and the third-most visited tourist attraction in Norway. When the train is in the centre of the track, the region of the wheels in contact with the rail traces out a circle which has the same diameter for both wheels. Friction-enhancing sand or an equivalent is needed. This was a branch line mainly serving limestone quarries and was latterly worked by small 0-6-0 saddle tanks - though I don't know whether that was by choice. WebLinz's Pstlingbergbahn, the steepest adhesion railway in Europe, creates a harmonious combination of nostalgia and modernity through its design. The inclusion of steep gradients on railways avoids the expensive engineering works required to produce more gentle gradients. The narrow gauge mining and Taplin, Michael; and Russell, Michael (2002). Often slope is calculated as a ratio of "rise" to "run", or as a fraction in which run is the horizontal distance and rise is the vertical distance. A funicular is a type of cable railway system that connects points along a railway track laid on a steep slope. Most rack railways are mountain railways, although a few are transit railways or tramways built to overcome a steep gradient in an urban environment. The maximum gradient on adhesion is 8% between Vetta Scorcola and Cologna stops. Replica trains are mostly used, but occasionally vintage steam trains from the late-nineteenth century make the 35-minute run through flower-studded meadows. Wilmington. The phenomenon of hunting was known by the end of the 19th century, although the cause was not fully understood until the 1920s and measures to eliminate it were not taken until the late 1960s. The Thamshavn Line was the first electric railway of Norway. UNESCO. In practice, the swaying is damped out below a critical speed, but is amplified by the forward motion of the train above the critical speed. steepest operating mainline grade in the USA was the 4.7% Saluda Built in 1882 at an Usui Pass, former Shin'etsu Main Line, Japan, Toden Arakawa Line (Tokyo Sakura Tram), Japan. In only 20 minutes, starting from Hauptplatz, its climbs Linz's local mountain. In practice, the minimum radius of turn is much greater than this, as contact between the wheel flanges and rail at high speed could cause significant damage to both. What is the steepest operating adhesion railroad grade in the USA? Some railway lines are so steep they require rack rails - toothed racks that the rails lock into using a cog or pinion. Braking when travelling downhill is also a limiting factor. The "factor of adhesion", being the weight on the driven wheels divided by the theoretical starting tractive effort, was generally designed to be a value of 4 or slightly higher, reflecting a typical wheel-rail friction coefficient of 0.25. including the Stockton & Darlington Railway (1825) and Liverpool & The worlds steepest adhesion railway grade is a 13.8% grade found on the tram network of LIsbon, Portugal. WebThe Bernina line is one of the highest alpine crossings in Europe and one of the steepest adhesion railway lines in the world. Replica trains are mostly used, but occasionally vintage steam trains from the late-nineteenth century make the 35-minute run through flower-studded meadows. The C&HP was ancient and bizzarly engineered. This may appear trivially simple from a superficial glance but it becomes extremely complex when studied to the depth necessary to predict useful results. Balsam Mountain, home of highest railroad station east of the Rockies; average grade about 4.0%, max 4.5%. High-speed railways commonly allow 2.5% to 4% because the trains must be strong and have many wheels with power to reach very high speeds. For very high speed, the minimum adhesion limit again appears appropriate, implying a radius of turn of about 13km. It links Rheineck station, in the municipality of Rheineck and the canton of St Gallen, with the village and health resort of Walzenhausen, in the canton of Appenzell Ausserrhoden. A steep grade railway is a railway that ascends and descends a slope that has a steep grade. WebThe adhesion railway relies on a combination of friction and weight to start a train. Rails and railway wheels are much stiffer than pneumatic tyres and tarmac but the same distortion takes place at the region of contact. If wheelsets are rigidly coupled together, this motion is restricted, so that coupling the wheels would be expected to introduce sliding, resulting in increased rolling losses. Grades of 5% are not uncommon on them. Adhesion is caused by friction, with maximum tangential force produced by a driving wheel before slipping given by: Usually the force needed to start sliding is greater than that needed to continue sliding. The steepest adhesion worked grade in the UK was Hopton Incline on the former Cromford and High Peak Railway, at 1 in 14 (7.14%). On this Wikipedia the language links are at the top of the page across from the article title. 16,640 feet above sea level at Tanggula Pass, China. There are steeper grades on at least one other tram system, that of Lisbon, but the Pstlingbergbahn is still among the world's steepest adhesion railways and has the steepest grade of any in Austria. WebMetros and pure commuter railways often also allow steeper gradients, over 4%, for the same reason.
