Rail transport is the transport of passengers and supplies by means of wheeled vehicles particularly designed to run down railways.

A railway/railroad track consists of two parallel iron rails, usually anchored vertical to beams, termed sleepers or ties, concrete, or steel to keep a steady space apart, or gauge. The rails and perpendicular beams are generally then placed on a base made of concrete or condensed earth and gravel in a bed of ballast to stop the track from buckling as the ground settles over time below and under the weight of the vehicles passing above. The vehicles traveling on the rails are arranged in a train; a string of individual powered or unpowered vehicles connected together, displaying markers.
