The Niddertalbahn: Bad Vilbel – Stockheim add-on for the Train Sim World series is an authentically detailed simulation of a German branch line as it appeared in the early 1990s. Developed by TrainSim Germany (TSG), this non-electrified route offers a distinct diesel-era experience across TSW 3, 4, 5, and 6.

Route & Setting

• Location and Length: The add-on covers the full, authentically recreated 31km (19-mile) single-track line in the Hesse region of Germany, connecting Bad Vilbel and Stockheim.
• Historical Era: The simulation is specifically set in the early 1990s, allowing players to operate services before later station modernizations and name changes occurred.

Included Locomotives & Rolling Stock

The focus is squarely on classic diesel traction of the Deutsche Bundesbahn era:

• DB BR 628.2: The primary diesel multiple unit (DMU) used for passenger services, presented in the classic white and mint livery.
• DB BR 365: A robust diesel shunter (a derivative of the V60) in a classic blue livery, dedicated to hauling seasonal freight.
• Es50 Wagons: Specific rolling stock included for the seasonal sugar beet freight operations.
• AI Services: To enhance immersion, the electrified mainlines surrounding Bad Vilbel feature AI train traffic using the iconic DB BR 103 and DB BR 110 locomotives.

Gameplay Features

The add-on provides a comprehensive gameplay package:

• A full 24-hour timetable and structured scenarios.
• A dedicated Journey Mode and collectible route tasks.
• Full compatibility with community creation tools, including the Livery Designer, Scenario Planner, and Creators Club.
