Transit tubes are the primary components of a Tube System to rapidly transport Duplicants from place to place within your colony. Tubes can only be entered with a Transit Tube Access and completely shield a Duplicant from whatever hazards the tube is run through whilst the Duplicant is inside. Like Heavi-Watt Wires, Transit Tubes cannot cross tiles, but a Transit Tube Crossing may be used in place of a tile.
Transit tubes require additional space to make a turn and cannot make a U-Turn.
- Transit tubes are faster than most other items in the game, excluding Fire Poles being used downward.
- While the tubes do protect Duplicants from harm, they are made of Plastic themselves, and are susceptible to its low melting point. Use caution with tubes around high heat.
- The tubes are likely a reference to the transit tubes seen in Futurama's New New York.
