Yes, it's like a generic word for this purpose. An instrument/machine that moves, or takes you or stuff from one point to another.

You can put it like "chandra" (moon) + "yaan" and it becomes "a vehicle that goes to the moon; or is built for a purpose related to moon"; or "vaayu" (air) + "yaan" and it becomes an air-plane. "jal" (water) + "yaan" and it's a ship.

In our trains there are "shayan" (sleeping) + "yaan" - here it means "coach", i.e. sleeper coaches as opposed to those sitting coaches.
