Transport Tubes

Transport Tubes are a fast way to move around on the Mars of the late 19th century. Each of the four cities, Argyre, Elysium, Hellas and Olympus has a station of these tubes that allow nearly instantaneous travel to the other cities.

In Martian Dreams, the tube system could only be accessed after getting into Olympus and repairing the power grid. Initially, the Argyre would end at a blocked metal gate, thanks to Raxachk blocking off the city and the station being located outside of it. Only after the Avatar's party forced its way into Argyre did its transport tube become useful again.
