When railways were invented, Doncaster became famous for steam trains. It was an important stop for trains travelling between Scotland and London. It is still an important stop today. A big factory for making trains was built in Doncaster. Some of the finest and fastest steam trains in the world were built in Doncaster. These trains include "The Flying Scotsman", "The Mallard", and "The Sir Nigel Gresley". The station also houses a unique Victorian themed bar on platform 3b.
