A fishplate joins two lengths of track. A fishplate, splice bar or joint bar is a metal connecting plate used to bolt the ends of two rails into a continuous track. The name is derived from fish, [1] a wooden reinforcement of a "built-up" ship's mast that helped round out its desired profile. [2] The top and bottom faces taper inwards along ...
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).
Long welded rail was hard to install manually. An early demonstration of mechanised track-laying with two 600 ft (180 m) lengths of long welded rail took place on the Fighting Cocks branch in 1958. The two lengths were loaded on ten wagons, attached to the existing track by a steel rope and drawn back at 30 ft (9.1 m) a minute.
Most modern railways use continuous welded rail (CWR), sometimes referred to as ribbon rails or seamless rails. In this form of track, the rails are welded together by utilising flash butt welding to form one continuous rail that may be several kilometres long. Because there are few joints, this form of track is very strong, gives a smooth ride ...
In June 1898, Henry Jules Caillet, who lived in 7 Boulevard St. Denis, Paris, granted a license to Eaton Devonshire of Chislehurst. Then in October 1898, the 'Monorail Portable Railway Company' was founded, which held the rights in Great Britain and the Commonwealth colonies. On November 17, 1905, an advertisement appeared in The Engineer for a ...
Grooved rail, used when track is laid in places traversed by other vehicles or pedestrians. A grooved rail, groove rail, or girder rail is a special rail with a groove designed for tramway or railway track in pavement or grassed surfaces (grassed track or track in a lawn). The head on the right-hand side of the rail bears the vehicle's weight.
Rail stressing. Stressing is a rail engineering process. It is used to prevent heat and cold tension after installation of continuous welded rail (CWR). Environmental heat causes CWR to expand and therefore can cause the fixed track to buckle. Environmental cold can lead to the contraction of the fixed railway track causing brittleness and cracks.
A rail fastening system is a means of fixing rails to railroad ties ( North America) or sleepers ( British Isles, Australasia, and Africa ). The terms rail anchors, tie plates, chairs and track fasteners are used to refer to parts or all of a rail fastening system. The components of a rail fastening system may also be known collectively as ...
