City Transport Simulator 2026 patch notes document ViewApp's continuous updates for PC, PlayStation 5, and Xbox Series X|S, addressing everything from core physics and force feedback wheels to expansive map DLCs. Following its initial April 14, 2026 release, the simulation has received systematic hotfixes and milestone patches that expand route building, overhaul ticketing mechanics, and refine urban transit operations across Tramau and Vienna.

The changelogs below trace every officially documented update, detailing major additions such as circular line construction, emergency traffic resets, passenger seating in free roam, and Vienna route integration.

Update History and Version Breakdown

The development cycle for City Transport Simulator 2026 has progressed through several numbered client builds and targeted hotfixes.

Update v2026.3.0: Vienna Expansion and Route Refinement

Released alongside the paid Vienna Expansion and all-in-one Vienna Edition, Update v2026.3.0 expanded the simulator beyond the fictional southern German backdrop of Tramau into a recreation of Austria's capital.

Vienna Network Integration

• Added real-world routes: Tram Line 37 (Schottentor to Hohe Warte), Tram Line 38 (Schottentor to Grinzing), and Bus Line 35A (Spittelau to Salmannsdorf).
• Added Night Bus Line N35 operating between Nußdorfer Straße and Salmannsdorf featuring lighter late-night traffic, longer service intervals, and reduced passenger volume.
• Modeled the authentic Remise Gürtel tram depot at 1:1 scale alongside more than 1,000 individually recreated real-world structures.
• Fleet additions introduced the ULF Type A and ULF Type B low-floor trams, the Citybus C2 solo bus, and the C2 articulated bus featuring Wiener Linien styling, custom driver cabs, and authentic operating sounds.

Systems and Handling Fixes

• Updated controls to support recent Logitech G HUB configurations.
• Stop markers and overhead navigation arrows now render earlier in the driver view.
• Adjusted passenger boarding distribution across all available vehicle doors.
• Updated the lighting engine, tuned graphics presets, and allowed custom express bus routes that skip Marienplatz.
• Resolved window fogging glitches, corrected tram door opening states, and fixed the Citybus C2 retarder functionality in stage 5.

Update v26.2.0: Express Lines, Audio, and Passenger Immersion

Update v26.2.0 focused heavily on route design flexibility and in-cabin simulation details.

Route and Operational Freedom

• Express Bus Service: Players can now configure express lines that deliberately skip intermediate stops, cutting journey times over long-distance routes.
• Dynamic Stop Skipping: Scheduled buses and trams are no longer forced to stop at every station if no passengers are actively boarding or requesting to alight.
• Seated Free Roam: Players exploring outside active shifts can now sit down in passenger passenger seats to ride lines across the city rather than being forced to stand.

PC Audio and IBIS Customization

• Enabled custom player audio files on PC to overwrite default stop announcements through the game's designated Announcements directory.
• Special automated announcements can now be manually triggered via compatible onboard IBIS units:
  • Vienna IBIS: Activated via Button 3.
  • Munich IBIS: Activated via the "Special Announcement" option.
  • Frankfurt IBIS: Activated via the Speaker icon.
  • Bus Ticket Printer: Activated via the Speaker icon.
  • Note: The Mannheim IBIS unit does not support manual special announcements.
• Added varied male and female passenger voice lines.
• Refined vehicle soundscapes for the E1, Tatra, ULF A1/B1, Flexity Vienna, GT6/GT8, R2.2b, and Tramlink, muffling passenger cabin noise realistically inside closed driver cabins.

Rolling Stock Mechanical Fixes

• E1 Tram: The dead man's warning system must now be confirmed manually using the dedicated dead man button, and the main switch animation was corrected.
• Flexity Tram: Windshield wipers can now be turned off with the same toggle button, button sounds were added to the left dash display, and rail brake/bell foot pedals are fully interactive.
• ULF Low-Floor Tram: Refined 3D model geometry and adjusted wheel-rail adhesion to prevent wheel lockups under heavy service braking.

Update v2026.0.3 and Hotfixes: Loops and Wheel Controls

Update v2026.0.3 answered major community requests regarding line pathing and hardware controls.

Closed-Loop Line Editor

The line editor allows circular routes where the route path starts and ends at the identical station platform. Once the loop is linked, the editor locks the closed circuit, calculates happiness metrics, and lets AI or player fleets run continuous ring services. A subsequent hotfix corrected analog station signs and passenger departure monitors to ensure departure schedules read accurately at loop termination points.

Advanced Steering Wheel Profiles

Force feedback settings can be configured independently for individual connected hardware devices. The patch added factory calibration profiles for tested wheel bases across multiple manufacturers, added a one-click reset to default values, and expanded custom key assignments:

• Directional turn signals for Moza and Aerosoft steering devices.
• Parking lights, low-beam headlights, and explicit headlight cut-off commands.
• Specific wiper speeds and intermittent modes.
• Windshield heating and ticket machine camera shortcut toggles.
• Foot-pedal and button mappings for secondary horns, gongs, and the E1 Geamatic brake release.

Environmental and Bug Corrections

• Added an on-demand weather adjustment slider directly within the in-game pause menu.
• Sub-zero freezing temperatures now render snow rather than rain.
• Fixed a bug where dynamic weather audio played persistent rain sound effects during clear skies.
• Reworked the traffic intersection around Marcoplatz to stop buses from getting trapped behind turning vehicles.
• Optimized 3D map assets in the Torijama Allee area to improve performance and fix related console crashes.

Update v2026.0.2: AI Traffic Reset and Fare Settings

Update v2026.0.2 resolved core gameplay bottlenecks that appeared during launch week.

Emergency AI Reset and Fare Management

• Reset Traffic Button: Accessible via the pause menu, this option immediately despawns all active AI roadway vehicles, rescuing players stuck in artificial traffic gridlocks or broken intersections.
• Fare Payment Selection: Operators can choose how passengers pay inside vehicles, selecting between Cash Only, Contactless Only, or Combined Cash and Contactless fare collection.
• Visual Gamma Control: A dedicated manual gamma slider was added to the graphics settings to correct brightness across varying monitor and TV setups.

Environment and AI Traffic Tuning

• Closed physical gaps under street curbs along Lilienstraße and aligned misplaced bridge rails on Friedrich Schneider Street.
• Corrected misaligned track masts at Hauptbahnhof West, removed floating billboard assets on Toriyama Allee, and removed wandering pedestrians spawned directly on tracks along Lichterallee.
• Addressed vehicle turn-blocking at Krankenhaus Nord and eliminated phantom stops where AI drivers sat idling indefinitely at green signals near Wasserturm.

Wheel Hardware and Troubleshooting Workarounds

While developer updates expanded manufacturer compatibility, specific hardware interactions require precise handling:

PS5 Thrustmaster Boot Loop Workaround

On PlayStation 5, connecting a Thrustmaster wheel (such as the T128) prior to launching the title can trigger an infinite save-data loading loop where the initial menu fails to load.

To bypass this issue:

1. Boot City Transport Simulator 2026 on your PS5 using the DualSense controller while the steering wheel is unplugged.
2. Wait until the title passes the initial loading sequence and reaches the main menu.
3. Connect the USB cable of your Thrustmaster wheel directly to the console.
4. Verify the peripheral under the device menu (it will frequently register as a Thrustmaster T-GT profile, which supports normal button reassignment and force feedback calibration).

AI Jam Troubleshooting

If AI vehicles ignore lane restrictions or block a tight turn at narrow junctions:

1. Hit pause to open the system menu.
2. Select the Reset Traffic option added in update v2026.0.2.
3. Resume driving to clear the surrounding intersection without incurring schedule penalty strikes.

Frequently Asked Questions

How do I build a circular loop route in City Transport Simulator 2026?

Open the Line Editor, begin laying your stops from your selected platform, and place intermediate stations along your path. Route the line back to your original starting platform and click it. The interface will display a notification confirming that the line is looping and that no further stations can be added. Save the path to complete the route.

Why does rain sound effect audio play when the sky is clear?

This was a known audio logic error where dynamic weather cycles triggered heavy rainfall audio cues despite clear visual skies. The bug was officially resolved in update v2026.0.3. If you still encounter this issue on older game installations, update to the latest build or cycle weather settings to "Clear" via the pause menu.

Can console players import custom stop announcements?

Custom audio import for transit announcements is supported exclusively on PC via local audio files placed inside the dedicated CTS 2026 Announcements directory. Console versions on PS5 and Xbox Series X|S can only trigger pre-recorded stock special announcements mapped to compatible IBIS devices.

How do you switch ticket sales to card only?

Open your route management settings or gameplay preferences and navigate to the ticketing configuration introduced in update v2026.0.2. Toggle the payment option to "Contactless Only." Passengers will tap card scanners at the onboard ticketing printer, removing manual coin dispensing and change calculation during your route.
