The sleepers are laid on the gravel bed where the panel track was. The sleeper train leaves the worksite loaded with sections of panel track. The sleepers, sometimes known as bi-bloc sleepers, are U41 twin block reinforced concrete, 2.4 m (7 ft 10 in.) wide, and weigh 245 kg (540 lb
The 1 ft 11 + 1 ⁄ 2 in (597 mm) gauge Lynton and Barnstaple Railway (1898 to 1935) in North Devon, experimented with concrete sleepers at a number of locations along the line. As the sleepers were cast to gauge, they were of little use outside the station areas on this very curvaceous line where gauge slackening was commonly required.
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 ...
Concrete sleepers may be cast with alternative gauge fittings in place, an example being those used during the conversion of the Melbourne–Adelaide railway from 1600 mm (5 ft 3 in) to 1435 mm (4 ft 8 + 1 ⁄ 2 in). Steel sleepers may have alternative gauge fittings cast at production, may be drilled for new fittings or may be welded with new ...
Sleepers are 8 ft 6 in (2.59 m) long, 10 inches (254 mm) wide and 5 inches (127 mm) deep. The two sleepers adjacent to a joint may be 12 inches (305 mm) wide where the formation is soft or the traffic is heavy and fast. Sleepers are mostly spaced 2 ft 7 in (0.79 m) apart (centre-to-centre) but are closer adjacent to fishplated rail joints where ...

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 ballastless track or slab track is a type of railway track infrastructure in which the traditional elastic combination of sleepers and ballast is replaced by a rigid construction of concrete or asphalt. It is considered the standard for high-speed and heavy haul railway lines. [1] It is also commonly used for urban tramways. [2]
