Concrete sleepers were first used on the Alford and Sutton Tramway in 1884. Their first use on a main line railway was by the Reading Company in America in 1896, as recorded by AREA Proceedings at the time. Designs were further developed and the railways of Austria and Italy used the first concrete sleepers around the turn of the 20th century.
Tracks for the layout can be either portable (i.e. removable), or permanent. The former may be of fairly simple welded steel construction, but the latter are usually built from miniature steel or aluminium rails attached to wooden, plastic or even concrete sleepers (US: ties), and put on a proper foundation of crushed stone ("track ballast"), just as in full size.
The Swiss Federal Railways replaced the sleepers and rubber shoes of the ballastless track in the 4.9-kilometre (3.0 mi)-long Heitersberg Tunnel between 2014 and 2016, whereas no maintenance of the concrete slab was necessary 39 years after the tunnel's opening. [4] [5]

Track with low vegetation or foot-of-rail (FOR): [2]: 76 Concrete sleepers are placed upon longitudinal concrete beams, and the space in between the sleepers is filled with topsoil instead of track ballast, with vegetation only reaching the base of the tracks. This has a reduced sound dampening effect, and the uniform green area is visually ...
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 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) each.
