Adhesion railway. Driving wheel of steam locomotive. An adhesion railway relies on adhesion traction to move the train, and is the most widespread and common type of railway in the world. Adhesion traction is the friction between the drive wheels and the steel rail. [ 1 ] Since the vast majority of railways are adhesion railways, the term ...
Balsam N.C. Balsam Mountain, home of highest railroad station east of the Rockies; average grade about 4.0%, max 4.5%. 1 of 2 grades on southern railways former Murphy branch that are +4% grade. Balsam Mountain has seen many runaways. It is still in service operated by the Blue Ridge Southern Railroad (Watco).
The Bernina railway line (‹See Tfd› German: Berninalinie; Italian: Linea del Bernina; Romansh: Lingia dal Bernina) is a single-track 1,000 mm (3 ft 33⁄8 in) metre gauge railway line forming part of the Rhaetian Railway (RhB). It links the spa resort of St. Moritz, in the canton of Graubünden, Switzerland, with the town of Tirano, in the ...
Slippery rail, or low railhead adhesion, [ 1 ][ 2 ][ 3 ] is a condition of railways (railroads) where contamination of the railhead reduces the traction between the wheel and the rail. This can lead to wheelslip when the train is taking power, and wheelslide when the train is braking. One common cause of contamination is fallen leaves that ...
Rack railway. The Pilatus Railway is the steepest rack railway in the world, with a maximum gradient of 48% and an average gradient of 35%. 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 ...
It is the steepest adhesion railway in Switzerland with a gradient of up to 8.0% and forms part of the network of the Appenzell Railways (AB) and the St. Gallen S-Bahn (S20, S21 and S22 services). The line's two branches were completed in sections between 1889 and 1904 by the St. Gallen-Gais-Appenzell-Altstätten Railway and the Trogen Railway.
The Flåm Line (Norwegian: Flåmsbana) is a 20.2-kilometer (12.6 mi) long railway line between Myrdal and Flåm in Aurland Municipality, in Vestland county, Norway. A branch line of the Bergen Line, it runs through the valley of Flåmsdalen and connects the mainline with Sognefjord. The line's elevation difference is 866 meters (2,841 ft); it ...
A locomotive with a factor of adhesion much lower [higher] 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 [above] 4 because the traction force at the wheel rim do not fluctuate as much.2605:E000:A983:4B00:E9:58F9:6FD4:C270 02:42, 20 ...
