A train is a form of rail transport consisting of a series of vehicles that usually run along a rail track to transport cargo or passengers.

Motive power is provided by a separate locomotive or individual motors in self-propelled multiple units.Although historically steam propulsion dominated, the most common modern forms are diesel and electric locomotives, the later supplied by overhead wires or additional rails.The word train comes from the Old French word trahiner, which itself derives from the Latin word trahere meaning to pull or draw.

This is a Hornby model of the London and North Eastern Railway (LNER) A1 class steam locomotive, the Flying Scotsman.The Flying Scotsman express passenger train service has been running between Edinburgh and London since 1862 when it was called the Special Scotch Express.Following locomotive modifications which enabled the service to run non-stop, the A1 class locomotive 4472 ‘Flying Scotsman’ (the model shown here) was used to haul the inaugural train of the new service from London on 1 May 1928.It successfully ran the 392 miles in a record at that time for a scheduled service.
