Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' ...

Mount Washington Cog Railway
The Mount Washington Cog Railway, also known as the Cog, is the world's first mountain-climbing cog railway (rack-and-pinion railway). The railway climbs Mount Washington in New Hampshire, United States. It uses a Marsh rack system and both steam and biodiesel-powered locomotives to carry tourists to the top of the mountain. Its track is built to a gauge, which is technically a narrow gauge, as it is less than a . It is the second steepest rack railway in the world after the Pilatus Railway in Switzerland, with an average grade of over 25% and a maximum grade of 37%. The railway is approximately long and ascends Mount Washington's western slope, beginning at an elevation of approximately above sea level and ending just short of the mountain's summit peak of . The train ascends the mountain at and descends at . Steam locomotives take approximately 65 minutes to ascend and 40 minutes to descend, while the biodiesel engines can go up in as little as 36 minutes. Most of the Mo ...

Rack Railway
A rack railway (also rack-and-pinion railway, cog railway, or cogwheel railway) is a steep grade railway with a toothed rack rail, usually between the running rails. The trains are fitted with one or more cog wheels or pinions that mesh with this rack rail. This allows the trains to operate on steep grades above 10%, which is the maximum for friction-based rail. 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 first cog railway was the Middleton Railway between Middleton and Leeds in West Yorkshire, England, United Kingdom, where the first commercially successful steam locomotive, ''Salamanca'', ran in 1812. This used a rack and pinion system designed and patented in 1811 by John Blenkinsop. The first mountain cog railway was the Mount Washington Cog Railway in the U.S. state of New Hampshire, which carried its first fare-paying passengers in 1868. The track was complet ...

Pilatus Railway
The Pilatus Railway (german: Pilatusbahn, links=no, PB) is a mountain railway in Switzerland and the steepest rack railway in the world, with a maximum gradient of 48% and an average gradient of 35%. The line runs from Alpnachstad, on Lake Alpnach, to a terminus near the Esel summit of Pilatus at an elevation of 2,073 m (6,801 ft), which makes it the highest railway in the canton of Obwalden and the second highest in Central Switzerland after the Furka line. At Alpnachstad, the Pilatus Railway connects with steamers on Lake Lucerne and with trains on the Brünigbahn line of Zentralbahn. History The first project to build the line was proposed in 1873, suggesting a and 25% maximal gradient. It was concluded that the project was not economically viable. Eduard Locher, an engineer with great practical experience, then proposed an alternative project with the maximum grade increased to 48%, cutting the distance in half. Conventional systems at the time could not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lynton And Lynmouth Cliff Railway
The Lynton and Lynmouth Cliff Railway is a water-powered funicular railway joining the twin towns of Lynton and Lynmouth on the rugged coast of North Devon in southwest England. Lynton and Lynmouth are separated by a high cliff, making it hard for people and goods to move between them. In the late 1800s, interest arose in building a funicular or cliff lift to join them. The civil engineer George Croydon Marks played a key role in both its design and bringing in financing from his business partner, Sir George Newnes. Local contractor Robert Jones was involved in designing the funicular's innovative braking system and the line's construction and maintenance in the first decades of its operation. In 1887, construction commenced and a year later, an Act of Parliament authorised the ''Lynmouth & Lynton Lift Company'' to operate it. The completed railway was opened on Easter Monday 1890; it has been in continuous use since. While early use was largely focused on moving freight, t ...

Funicular Railway
A funicular (, , ) is a type of cable railway system that connects points along a railway track laid on a steep slope. The system is characterized by two counterbalanced carriages (also called cars or trains) permanently attached to opposite ends of a haulage cable, which is looped over a pulley at the upper end of the track. The result of such a configuration is that the two carriages move synchronously: as one ascends, the other descends at an equal speed. This feature distinguishes funiculars from inclined elevators, which have a single car that is hauled uphill. The term ''funicular'' derives from the Latin word , the diminutive of , meaning 'rope'. Operation In a funicular, both cars are permanently connected to the opposite ends of the same cable, known as a ''haul rope''; this haul rope runs through a system of pulleys at the upper end of the line. If the railway track is not perfectly straight, the cable is guided along the track using sheaves – unpowered pulleys that ...

Stoosbahn
The Stoosbahn, also known as the Schwyz–Stoos funicular or ''Standseilbahn Schwyz–Stoos'', is a funicular railway in the Swiss canton of Schwyz. It connects the Hintere Schlattli in the municipalities of Muotatal, Morschach, and Schwyz with the village and mountain resort of Stoos, above Morschach. On a length of 1.7 kilometres (1.1 mi), it overcomes a height difference of 744 metres (2,441 ft). It opened on 15 December 2017 and replaces the , operating since 1933 on a different route. The carriages are barrel-shaped and rotate to maintain a level floor surface for passengers. Construction took five years and cost 52 million Swiss francs. The new line has a maximum gradient of 110% (47.7°) and is the steepest funicular railway in Switzerland and Europe, superseding the Gelmerbahn. It has been widely claimed to be the steepest in the world, and although the Katoomba Scenic Railway in Australia is steeper, with a maximum gradient of 122%, it uses a winch syste ...
