Rail transport is the transport of passengers and goods by means of wheeled vehicles specially designed to run along railways or railroads. Rail transport is part of the logistics chain, which facilitates the internationaltrading and economic growth in most countries.A typical railway/railroad track consists of two parallel rails, normally made of steel, secured to cross-beams, termed sleepers (U.K.) or 'ties' (U.S.). The sleepers maintain a constant distance between the two rails; a measurement known as the 'gauge' of the track. To maintain the alignment of the track it is either laid on a bed of ballast or else secured to a solid concrete foundation. The whole is referred to as permanent way (UK usage) or right-of-way (North American usage).
