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 following are lengths of single sections produced by steel mills, without any thermite welding. Shorter rails may be welded with flashbutt welding, but the following rail lengths are unwelded. (1767) Richard Reynolds laid the first iron rails at Coalbrookdale. [21] (1825) 15 feet (4.57 m) Stockton and Darlington Railway 5.6 lb/yd (2.78 kg/m)
Pre-war experiments with long welded rail lengths were built upon, and in the years from 1960 long rail lengths were installed, at first on hardwood sleepers but soon on concrete sleepers. For example, the first long welded rail (almost 1 mi or 1.6 km) on the UK's East Coast Main Line was laid in 1957, just south of Carlton-on-Trent , resting ...
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).
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 other ...
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 ...
The new rails usually need to be prepared prior to the arrival of track renewal train. Rails are delivered to the center of the track. Those rail pieces are welded by track workers to form continuous welded rail (CWR) and left at the center of the track at the exact position required by the track renewal train to pick up at its arrival.
