Trams are a terran vehicle. They were in use by at least 2505.

A tram was in usage at Research Station EB-103 under the control of the Umojan Protectorate, where it connected the main labs to the shuttle bay. In 2505 the labs came under attack from the Terran Dominion in an attempt to capture Sarah Kerrigan and Jim Raynor. The tram was attacked to stop them from escaping, but the tram was defended and the two made it to the shuttle bay.[1]
