A cross-section through the Great Western Railway's baulk road, made with bridge rail. Bridge rail is a rail with an inverted-U profile. Its simple shape is easy to manufacture, and it was widely used before more sophisticated profiles became cheap enough to make in bulk.
As originally constructed, each roadway deck was 18 feet (5.5 m) wide, with two 9-foot (2.7 m) lanes; but because of the railroad component, it is unusually flat. Normally, bridges its height have a hump, but this bridge was designed flat to facilitate rail traffic. [10] The bridge is a favorite railfan location.
The bridge gets its "number 1" name from the fact that it is the farthest downstream crossing of the Cuyahoga River proper before it empties into Lake Erie (the only other crossing is the Old River Bridge, which crosses the former course of the Cuyahoga). The bridge is of similar design to many of the other railroad bridges in the Cleveland area.
An example of the potential complexity of grade separation, seen in the Jane Byrne Interchange in Chicago Seven various overpasses for grade separation in Spain near Barcelona Rail-rail grade separation in Xiaoshan, China The concept of grade separation includes all transport modes, such as a simple pedestrian bridge over rail tracks.
Suspension bridge (more precisely, suspended-deck suspension bridge): the most familiar type. Though technically all the types listed here are suspension bridges, when unqualified with adjectives the term commonly refers to a suspended-deck suspension bridge. This type is suitable for use by heavy vehicles and light rail. The main cables are ...
The railway companies became persuaded that the traditional bullhead forms of track needed revision, and after some experimentation a new flat bottom rail format was adopted. The British Standard sections were unsuitable and a new profile, a 109 lb/yd (54 kg/m) rail, was made the new standard.
Rail profile Rail profiles for flat-bottom and bullhead rails The cross section shape of rail. There are many rail profiles, often specific to individual railroads. Rails must be periodically scanned electronically, the data inspected and analysed, then re-profiled with rail grinding machines to maintain the safe and proper rail profile. Rails ...
