A short note on Railways
Rail transport is the transport of passengers and supplies by means of wheeled vehicles mainly designed to run down railways.
A railway/railroad track includes of two parallel iron rails, generally 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 normally then placed on a base made of concrete or condensed earth and gravel in a bed of weight 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 placed in a train; a string of individual powered or unpowered vehicles joined together, displaying markers.
