Trainz 22: OBB Bmz 21-90 604

The OBB Bmz 21-90 604 DLC for Trainz Railroad Simulator 2022 was developed by i29tsro and published by N3V Games. It was released on 20 May 2025 and adds a faithfully recreated Austrian passenger coach to the simulator. This content focuses on bringing a piece of European rail heritage into the game with a high level of detail and authenticity.

The coach included in the DLC is based on the OBB Bmz 21-90 series, built between 1976 and 1982 by the Simmering-Graz-Pauker works. It is presented in the classic Austrian State Railways white and red livery and comes with a detailed interior and sliding doors. The model features full PBR texturing, animated couplers and air hoses, sound effects for brakes and buffer contact, HVAC system sounds, editable destination boards, and lighting for both interior and exterior night modes.

Promotion for the DLC was tied into the broader marketing of Trainz Railroad Simulator 2022. The publisher emphasized the attention to detail and the addition of a European coach model to appeal to fans interested in expanding their game with authentic rolling stock from different regions. The DLC was made available through both Steam and the Trainz Portal, making it easy for players to access.

At launch, the OBB Bmz 21-90 604 DLC did not immediately gather many reviews, but within the Trainz community it was noted for its craftsmanship and accuracy. Players who focus on European operations welcomed the inclusion of this coach, appreciating its realism and historical value. It was seen as a strong addition to the library of international content for Trainz 2022.
