A City Transport Simulator 2026 Steam key activates the full urban simulation developed by ViewApp and published by ViewApp - CTS. The standard base game retails for $39.99 on the official Steam store. If you previously purchased the original City Transport Simulator before April 14, 2026, you do not need to buy a new key, as the base game upgrade and existing DLC licenses transfer to your library at no extra cost.
New players and returning drivers looking to expand into real-world networks like the Vienna expansion can purchase keys across official storefronts, direct developer portals, and digital key retailers.

Frequently Asked Questions
Do existing City Transport Simulator owners need to buy a new Steam key?
No. Players who owned the predecessor, City Transport Simulator, on Steam prior to April 14, 2026, receive City Transport Simulator 2026 for free. Owned DLC packages from the previous release also transfer into CTS 2026 at no extra charge. Anyone purchasing after April 14, 2026, must buy a separate copy.
What controllers can I use with the Steam version?
The Steam version includes full controller support. You can drive buses and trams using a keyboard, mouse steering, standard gamepads (including Xbox controllers), joysticks, or supported steering wheels with preconfigured hardware profiles.
Can custom route lines be built in the Vienna DLC?
No. Unlike the fictional map of Tramau, where players can create custom routes and lines using the Line Editor, the Vienna expansion is a real-world recreation built using fixed, authentic timetables on real lines (such as tram lines 37 and 38, or bus line 35A/N35). Custom route generation is restricted to fictional maps.
Are custom audio announcements supported on all platforms?
Custom audio station announcements can only be imported and modified using custom audio files on PC. Console versions on Xbox Series X/S and PlayStation 5 do not support external audio file modification.
