Underground trams and tram-trains

Tram construction has an underground editing mode, while compatible light-rail vehicles can also transition onto railway infrastructure.

The confirmed picture

What we know

Underground mode helps edit tracks below surface structures. ↗

Tram-trains follow road rules on streets and rail signaling rules on railway tracks. ↗

Cargo trams can use separately attached wagons. ↗

How to approach the decision

Editorial planning advice based on the confirmed systems above.

  1. Choose the intended surface, underground and regional sections first.
  2. Verify the selected vehicle’s rail capability before connecting the systems.
  3. Treat station access, signaling and cargo handling as separate checks.

A mistake to avoid

Do not assume that every tram can run on railway tracks. Compatibility must be checked per vehicle.

Verify at launch

What still needs live data

Exact numerical values, release-build menus and reproducible gameplay tests will be added only after verification.

Exact values and operating advice are added after testing against a recorded game build. Check the source date before relying on a number.
