A railway track (CwthE and UIC terminology) or railroad track (NAmE), also known as permanent way (CwthE) [1] or "P Way" (BrE [2] and Indian English), is the structure on a railway or railroad consisting of the rails, fasteners, sleepers (railroad ties in American English) and ballast (or slab track), plus the underlying subgrade.
A transfer table contains two tracks with different configurations. The table is moved sideways or rotated [3] to choose the configuration that connects the track that the incoming train will be traveling from and to. Using transfer table as a switch or a rotary switch allows the center rack rail to be aligned for the cog wheels to continually ...
Too tight a 'crest' curve could result in the train leaving the track as it drops away beneath it; too tight a 'trough' and the train will plough downwards into the rails and damage them. More precisely, the support force R exerted by the track on a train as a function of the curve radius r, the train mass m, and the speed v, is given by
Train wheels rolling over the spikes loosened them, allowing the rail to break free and curve upwards sufficiently that a car wheel could get beneath it and force the end of the rail up through the floor of the car, writhing and twisting, endangering passengers. These broken rails became known as "snake heads". [14]
After an intervening period of mixed-gauge operation (tracks were laid with three rails), the Great Western Railway finally completed the conversion of its network to standard gauge in 1892. In North East England, some early lines in colliery ( coal mining ) areas were 4 ft 8 in ( 1,422 mm ), while in Scotland some early lines were 4 ft 6 in ...
The first American locomotive at Castle Point in Hoboken, New Jersey, c. 1826 The Canton Viaduct, built in 1834, is still in use today on the Northeast Corridor.. Between 1762 and 1764 a gravity railroad (mechanized tramway) (Montresor's Tramway) was built by British Army engineers up the steep riverside terrain near the Niagara River waterfall's escarpment at the Niagara Portage in Lewiston ...
A turntable for the Central Railroad of New Jersey. Turnplates at the Park Lane goods station of the Liverpool and Manchester Railway in 1831. Early wagonways were industrial railways for transporting goods—initially bulky and heavy items, particularly mined stone, ores and coal—from one point to another, most often to a dockside to be loaded onto ships.

The Grizzly Flats Railroad (GFRR) was a 3-foot (914 mm) narrow-gauge heritage railroad owned by Disney animator Ward Kimball at his home in San Gabriel, California. The railroad had 900 feet (274.3 m) of track, and was operated from 1942 to 2006. It was the first full-size backyard railroad in the United States.
