The difference between rail and train seems to be confusing as rail and trains are used in same context. However the literal meaning of both is different. Rail is defined as the track generally made by setting two parallel rows of steel and iron and this track is used by trains to move from one place to the other. It can also be defined by saying that a train is a mode of transportation and it runs on these specially laid tracks of iron rails known as railway track (or rail).
