Answer
Subways and underground construction in Transport Fever 3
Underground construction is in. Urban Games lists underground tram building among the new traffic management tools. A dedicated subway system has not been described in the same detail.

Underground transport is one of the reasons people keep asking about Transport Fever 3's infrastructure. The short version: underground construction is confirmed, and the official description points at trams rather than a separate metro system.
What Urban Games has said
The official First Look: Infrastructure video describes improved traffic AI, flexible road construction and modular stations. Within that list it names underground tram construction as one of the traffic management options, alongside better urban planning and pollution control.
Underground construction is described as a tool for planning and pollution control. Moving a line below ground is one way to keep noise out of a dense district.
Why this matters for city building
- Surface capacity is finite. A city that grows around your network eventually runs out of room at street level.
- Noise affects growth. Vehicles with poor maintenance emit more noise and pollution, so burying a busy line has a mechanical payoff.
- Modular stations change what is possible. The station pieces are meant to be assembled rather than picked from a fixed list.
What is still unconfirmed
There is no official description of a metro system with its own rules, its own vehicles and its own station set. If you are looking for the kind of subway layer that city builders use, treat that as unconfirmed until the game ships.
This page will be rewritten with specifics once the release build is available and underground construction can be tested directly.
FAQ
Does Transport Fever 3 have a subway system?
Urban Games has confirmed underground construction as part of the traffic management toolkit. It has not described a separate metro mode the way some city builders do.
Can I build tram lines underground?
That is the example the official infrastructure video gives. Building trams underground is listed alongside the improved traffic management options.
