Locomotive
A locomotive was a large self-propelled workhorse vehicle used to provide the drive power for a train.

It was typically powered by steam, electricity or diesel, that was utilized for transporting freight or passenger cars along a railroad.

After Jonathan Archer restored a damaged timeline, a locomotive could be seen in the time stream as the timeline realigned itself. ()

Beverly Crusher's holodeck simulation of the Orient Express featured the locomotive, along with the rest of the train. ()
