Tram engine

A tram engine is a piece of terran technology used to propel trams. Six of these engines powered the tram by Sarah Kerrigan and Jim Raynor to reach the shuttle bay during the Dominion's attack on the Umojan Protectorate facility Research Station EB-103. While en route to the shuttle bay, Kerrigan and Raynor had to protect the tram engines from Dominion forces.
