A plateway is an early kind of railway, tramway or wagonway, where the rails are made from cast iron. They were mainly used for about 50 years up to 1830, though some continued later. Plateways consisted of L-shaped rails, where the flange on the rail guides the wheels, in contrast to edgeways, where flanges on the wheels guide them along the ...
Stoney Creek was the highest timber bridge ever built, and at the time was the second highest bridge in North America [1] with reference to deck height, rather than structural height. Deck height is the maximum vertical drop from the bridge deck to the ground or water surface below. However, various sources yield a range of height measurements ...
The railway track or permanent way is the elements of railway lines: generally the pairs of rails typically laid on the sleepers or ties embedded in ballast, intended to carry the ordinary trains of a railway. It is described as a permanent way because, in the earlier days of railway construction, contractors often laid a temporary track to ...
This type of rail was known as the plate-rail, tramway-plate or way-plate, names that are preserved in the modern term "platelayer" applied to the workers who lay and maintain the permanent way. [13] The wheels of flangeway wagons were plain, but they could not operate on ordinary roads as the narrow rims would dig into the surface.
The Royal Albert Bridge is a railway bridge which spans the River Tamar in England between Plymouth, Devon and Saltash, Cornwall. Its unique design consists of two 455-foot (138.7 m) lenticular iron trusses 100 feet (30.5 m) above the water, with conventional plate-girder approach spans. This gives it a total length of 2,187.5 feet (666.8 m).
A railroad tie, crosstie (American English), railway tie (Canadian English) or railway sleeper (Australian and British English) is a rectangular support for the rails in railroad tracks. Usually laid perpendicular to the rails, ties transfer loads to the track ballast and subgrade, hold the rails upright and keep them spaced to the correct gauge.
The rail profile is the cross sectional shape of a railway rail, perpendicular to its length. Early rails were made of wood, cast iron or wrought iron. All modern rails are hot rolled steel with a cross section (profile) approximate to an I-beam, but asymmetric about a horizontal axis (however see grooved rail below).
Wilburton Trestle. / 47.602647; -122.181208. The Wilburton Trestle is a historic wooden railway trestle in Bellevue, Washington. Measuring 102 feet (31 m) high and 975 feet (297 m) long, it is the longest wooden trestle in the Pacific Northwest. [citation needed] The trestle carried a single track of a former Northern Pacific branch line over a ...
