A locomotive is the engine part of a train - the powerful car at the front that pulls all the other cars along the track. People sometimes use "locomotive" for the whole train too, especially old steam trains. As a more formal adjective, "locomotive" can describe anything related to the ability to move from place to place, though this use is rare and mostly shows up in science or medical writing, like "locomotive ability" meaning the ability to walk or move around.
