Rail Crane Rail SPA Crane (750 mm) Czech PW maintenance crane Electric crane replacing track on the Toronto streetcar system (1917). A railway crane (North America: railroad crane, crane car or wrecker; UK: breakdown crane) is a type of crane used on a railway for one of three primary purposes: freight handling in goods yards, permanent way (PW) maintenance, and accident recovery work.
16 mm to 1 foot or 1:19.05 is a popular scale of model railway in the UK which represents narrow gauge prototypes. [1] The most common gauge for such railways is 32 mm (1.26 in), representing 2 ft (610 mm) gauge prototypes.
The NMRA published alternative, more accurate and realistic standards for track and wheels sheet in S-1.1 These model railway standards are based on the full size prototype standards and the scale model operational reliability is therefore reduced in comparison to the models conforming to the normal NMRA standards.
The most common use of the term "track gauge" refers to the transverse distance between the inside surfaces of the two load-bearing rails of a railway track, usually measured at 12.7 millimetres (0.50 inches) to 15.9 millimetres (0.63 inches) below the top of the rail head in order to clear worn corners and allow for rail heads having sloping ...
Heavier rail can support greater axle loads and higher train speeds without sustaining damage than lighter rail, but at a greater cost. In North America and the United Kingdom, rail is graded in pounds per yard (usually shown as pound or lb), so 130-pound rail would weigh 130 lb/yd (64 kg/m). The usual range is 115 to 141 lb/yd (57 to 70 kg/m).
The earliest rail chairs, made of cast iron and introduced around 1800, were used to fix and support cast-iron rails at their ends; [2] they were also used to join adjacent rails. [ 35 ] In the 1830s rolled T-shaped (or single-flanged T parallel rail ) and I-shaped (or double-flanged T parallel or bullhead ) rails were introduced; both required ...
