[0002] Railway transportation is a land transportation method that uses locomotives to pull train vehicles on two parallel rails. The traditional method is steel wheel travel, but the broad definition of railway transportation also includes non-steel wheel travel methods such as magnetic levitation trains, cable cars, ropeways, etc., or rail transportation. Rails can provide an extremely smooth and hard medium for train wheels to roll on with minimal friction, making people on them feel more comfortable, and it can also save energy.
