Bielefeld gibt’s doch gar nicht!
Bielefeld doesn't even exist!
Add-on Bielefeld is a map project for the bus simulator OMSI 2 that recreates parts of the city of Bielefeld, Germany.
The first release will include the real bus lines 38 and 138, as well as the Sieker depot. The map is being developed with a strong focus on detail, featuring custom buildings, realistic streets, traffic systems, and local infrastructure based on their real-life counterparts.
Rather than relying heavily on default OMSI assets, the developers have created a large amount of custom content to better capture the character of the city. Ongoing development aims to expand the network with additional routes and areas, further increasing the scope and realism of the project.
Ein herzliches Hallo aus Neuendorf!
A warm hello from Neuendorf!
We find ourselves in a modern, dynamic city that has changed in many ways since the 1980s. Neuendorf has managed to preserve the charm of a medium-sized West German town while developing a new, modern identity.
Neuendorf 2025 is a heavily revised and modernized version of the fictional Neuendorf city map for the bus simulator OMSI 2.
It is a rebuilt urban bus network set in a mid-sized German-style city, updated to a “modern-day” version of Neuendorf with new infrastructure, redesigned streets, additional districts, and expanded or reworked bus routes.
A City in Motion
The train station has been transformed from a rather plain, functional hub into a modern transportation center. Following its extensive renovation, the Kurfürstenbrücke now shines in new splendor. The downtown area around the City Theater has been extensively redesigned and is now a lively gathering place with pedestrian zones, cafés, and green spaces. Even the zoo, a popular destination for families, has been renovated and now offers improved facilities for visitors.
Public transportation in Neuendorf has also undergone an impressive transformation. After the Mercedes-Benz O305 standard buses were phased out, the fleet successfully transitioned to Solaris vehicles. Since the 2000s, Solaris Urbino buses have been operating throughout the city, offering a higher level of comfort. Articulated buses were also introduced for the first time; these are used primarily on heavily traveled routes and have significantly increased capacity.
Since 2018, Neuendorf has been using the latest Solaris Urbino models, which are not only visually appealing but also more energy-efficient. These buses are set to gradually replace the older Solaris buses in order to make local public transportation even more modern and environmentally friendly. At the same time, the depot, which was previously located on Rudolf-Diesel-Straße, was moved to a new, more spacious location due to space constraints.
The city bus routes 301, 302, and 311—some of which are new—as well as route 312 have been further optimized to ensure better frequency and connections. The short factory shuttle connecting the Böttcherwerke to the train station has also been adapted to meet the needs of commuters. Thanks to the improved schedules, it is now easier than ever to get around Neuendorf comfortably by bus.
