City Transport Simulator 2026 Vienna route 37 is one of two authentic tram routes added in the Vienna Expansion, operating between the central terminus at Schottentor and the northern district terminus at Hohe Warte. The line shares tracks with tram line 38 through the inner city before branching off past Nußdorfer Straße into quieter residential and embassy areas. Unlike routes in the fictional city of Tramau, route 37 follows fixed real-world Austrian timetables and geometry recreated by developer ViewApp.
Route 37 Path and Key Landmarks
Tram line 37 begins at Schottentor in a dedicated underground turning loop and tunnel section, which is the first drivable tram tunnel in City Transport Simulator 2026.
On inbound trips approaching the city center, drivers pass the Josefinum (Vienna's Museum of Medical History) after the turn at Spitalgasse, followed by the Votive Church. The tracks continue toward Nußdorfer Straße, a major transport hub where line 37 intersects with tram line 38 and bus line 35A beneath the historic city rail arches where the U6 elevated line runs.
After leaving Nußdorfer Straße, line 37 branches away from line 38's path toward Grinzing. The route proceeds through quieter streets lined with embassies, museums, and Viennese cafés before reaching its northern terminus at Hohe Warte. The Hohe Warte stop features a large, single-track turning loop where drivers turn their vehicles around for the inbound trip back to Schottentor.
Compatible Vehicles for Route 37
While the expansion includes the first-generation Ultra Low Floor (ULF) trams, the game allows players to operate any compatible tram in their CTS fleet on Vienna route 37.
The primary vehicles bundled with the route are the original ULF A and ULF B trams, designed in Wiener Linien livery with rectangular headlights, interior indicators, and roof-mounted airflow vents rather than modern air conditioning units:
| Vehicle Model | Type / Segment Count | Overall Length | Seated Capacity | Total Passenger Capacity | Primary Characteristics |
|---|---|---|---|---|---|
| ULF A | Short Ultra Low Floor (5 segments) | Approx. 24.2 m | 42 seats | 136 passengers | Original cab layout, interior contactor switch audio, compact turning footprint |
| ULF B | Long Ultra Low Floor (7 segments) | Approx. 35.5 m | 56 seats | 213 passengers | Extended cabin length, 157 standing places, authentic braking dynamics |
| ULF A1 / B1 | Second-generation low floor (CTS Base Game) | Approx. 24.2 m / 35.5 m | Matches A / B configuration | Matches A / B configuration | Revised headlight housing, updated IBIS system, modern passenger cabin elements |
| Flexity Wien | Modern low-floor articulated tram (Separate DLC) | Multi-segment articulated | 160 passengers total | High-capacity modern cabin | Asynchronous drive, functional climate control, 70 km/h top speed |
| E1 Wien | Classic high-floor tram (Separate DLC) | Historic articulated car | Standard legacy configuration | Standard passenger capacity | In service from 1966 to 2022; manual deadman switch, traditional pedal/switch controls |
Players who own other tram DLCs, such as the StadtRegioTram or the Tatra KT4D, can also deploy them on route 37 in Sandbox or Timetable modes.
Gameplay Systems and Driving Mechanics
Driving route 37 introduces specific systems tied to the Vienna update:
- Timetable Operations: The Vienna network relies on authentic real-world schedules rather than user-generated networks. You cannot redraw or reroute line 37 in the line editor.
- Skippable Stops: Introduced in Update 26.2.0, drivers do not have to come to a complete halt at minor intermediate stops along line 37 if no passengers request a stop and no pedestrians are waiting on the platform. This helps maintain tight schedule margins.
- Vienna IBIS and Special Announcements: The cab features a Vienna-spec IBIS console. Players can trigger special announcements by pressing Button 3 on the device. On PC, players can add custom audio files into the game's announcements directory.
- Depot Access: Operations connect to the recreated Remise Gürtel tram depot. Spanning roughly two hectares, this depot features three maintenance halls, including the historic brick-facade Hall 2 dating back to 1901.

Frequently Asked Questions
Can you modify or create custom branches on Vienna route 37?
No. Because Vienna is modeled as an authentic real-world environment with over 1,000 specific architectural assets, custom line building is disabled for this map. Custom line creation remains exclusive to the fictional city of Tramau.
Where does route 37 terminate on both ends?
Route 37 runs between the underground turning loop at Schottentor in central Vienna and the single-track surface turning loop at Hohe Warte in the north.
Can older Vienna trams like the E1 run on route 37?
Yes. If you own the classic E1 Wien tram DLC, you can select and drive it across route 37 alongside modern low-floor vehicles like the ULF and Flexity.
