The crosstie spacing of mainline railroad is approximately 19 to 19.5 inches (48 to 50 cm) for wood ties or 24 inches (61 cm) for concrete ties. The number of ties is 3,250 wooden crossties per mile (2,019 ties/km, or 40 ties per 65 feet) for wood ties or 2,640 ties per mile for concrete ties.
The Railway Tie Association (RTA) is a trade association in the railroad and rail transit industry. The purpose of the RTA is to promote the economical and environmentally sound use of wood crossties . [ 1 ]
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.
Many railways use large wood screws, also called lag screws, to fasten the tie plates (or baseplates) to the railroad ties. Tie plates came into use around the year 1900, before which time flanged T rail was spiked directly to the ties.
Axe ties are railway ties (or sleeper) [1] that are hewn by hand, usually with a broadaxe.There are 2,900 ties per mile of track on a first class railroad. [clarification needed] The early railways would not accept ties cut with a saw, as it was claimed that the kerf of the saw splintered the fibres of the wood, leaving them more likely to soak up moisture causing premature rot.

In the deck-type bridge, a wood, steel or reinforced concrete bridge deck is supported on top of two or more plate girders, and may act compositely with them. In the case of railroad bridges, the railroad ties themselves may form the bridge deck, or the deck may support ballast on which the track is laid.
Tie cranes were developed to speed up and automate the labor-intensive task of moving railroad ties, which typically weigh over 100 pounds (and as much as 500 pounds for concrete ties). Before tie cranes, track workers would move ties by hand, using tools such as tie tongs and lots of muscle.
