Tram (Earth-5875)

A tram is a rail vehicle which runs on tramway tracks along public urban streets, military facilities and space stations. Most tramways are powered by electricity.

History
Trams have historically been civilian-based, although many came to be adopted by the UNSC in many of their facilities and space stations.

A tram system was constructed in a covert Office of Naval Intelligence excavation site beneath Sword Base, on Reach. Much like an elevator, this tram was able to change its orientation, and featured a holographic viewscreen. Noble Team used this tram on August 29th, 2552, during the Fall of Reach, to meet with Dr. Catherine Halsey.

orbital defense platforms also feature tram systems that run through the whole station. A tram was used by John-117 and SgtMaj Avery Johnson moments before the Battle of Earth, to reach Cairo Station's bridge.
