OMSI 2 Add-on Vienna 2 - Line 23A is a bus simulation add-on for the PC game OMSI 2. Players take on the role of a bus driver operating faithfully recreated vehicles from Wiener Linien on the real-world route of Line 23A through Vienna's 22nd district. The add-on emphasizes authentic cockpit controls, detailed animations, and realistic audio to recreate everyday service on this urban line.
Gameplay
The core loop centers on operating two articulated bus models: the NG 235 M18 from the first low-floor generation and the GU 240 M18 from the final high-floor generation. Both feature fully functional cockpits with numerous interactive elements and animations that respond to driver inputs during acceleration, braking, and door operations. Realistic sound design captures engine notes, interior ambiance, and external traffic noise to heighten immersion on the modeled streets.
Routes run through accurately recreated Vienna streets and buildings, incorporating many custom objects and scenery details that match the real environment. Drivers encounter AI-controlled traffic that includes passenger cars, other buses, trains, trams of types E1-c3 and ULF, and subway trains of type U. Additional AI elements feature city trains of class BR 4020 and Taurus locomotives BR 1116 from the Austrian Federal Railways, along with newly animated cars and motorbikes. Original Wiener Linien bus stop announcements play at the correct locations, and multiple traffic routings reflect changes before and after 2006.
The layout offers varied challenges through different path options, such as the pre-2006 alignment ending at Kagran U to Hirschstetten am Heidjöchl and the later routing from Kagraner Platz U to Hausfeldstraße S. Real timetables govern service patterns, requiring attention to schedules while navigating the detailed urban setting.
Game Modes
Players select from several route variants of Line 23A, each presented with its original timetable for scheduled service runs. These options allow repeated drives under changing traffic conditions and routing adjustments that reflect historical updates to the line. The add-on supports free exploration of the map alongside structured timetable-based operations that replicate typical daily duties for a Wiener Linien driver.
Both bus generations are available across the variants, letting drivers compare handling differences between high-floor and low-floor designs on the same streets. The system integrates with the base OMSI 2 simulation framework, where AI traffic density and passenger interactions form part of every session.
Route and Scenery Details
The modeled area focuses exclusively on Vienna's 22nd district, with streets, intersections, and landmarks built from real-world references. New objects and street models enhance authenticity, including period-accurate elements up to the year 2005 and post-2006 configurations. This attention to detail extends to bus stops, signage, and surrounding architecture that match the actual locations served by Line 23A.
Compatibility with the companion add-on Wien 1 - Line 24A allows shared departure points and combined operations, expanding the available driving variety without altering the core single-line focus of this release.
