Train Sim World 7: London Overground Mildmay line: Stratford - Willesden Junction Route Add-On is a train simulation game for PC that adds a detailed section of London's suburban rail network to the series. Players operate the Class 378 Capitalstar electric multiple unit along a 12-mile stretch with 18 stations between Stratford and Willesden Junction. The add-on emphasizes realistic driving of frequent commuter services on a busy urban corridor that connects several London boroughs while linking to other main lines.
Gameplay
The core loop centers on operating the dual-voltage Class 378/2 in its original London Overground livery. Drivers manage acceleration, braking, and speed limits on a route with short station intervals that demands constant attention. The cab features accurate controls and instrumentation for the Electrostar family, including overhead AC and third-rail DC power systems. Suspension and handling replicate real-world performance through the SimuGraph vehicle dynamics engine.
Scenery includes dense urban environments with landmarks such as the Olympic Park and HS1 tunnel approaches. Road traffic features London black cabs and red double-decker buses, while AI B07 Docklands Light Railway units appear at Stratford. Route hopping allows seamless transitions on foot to connected lines when those routes are owned separately.
Game Modes
Journey Mode links training modules, scenarios, and scheduled services into a progressive experience. The Training Center provides an accessible tutorial for the Class 378. Five scenarios present specific operational challenges, and an authentic timetable supports regular 8-trains-per-hour commuter runs in both directions with all-stop patterns.
Free Roam enables exploration of the route and rolling stock without time constraints. Timetable layers introduce additional playable freight traffic and AI services drawn from other London routes. Route Tasks offer optional objectives to complete during sessions. The Scenario Planner and Livery Designer tools support custom content creation shared through the Creators Club.
Route and Rolling Stock Details
The Mildmay line section runs through Brent, Camden, Hackney, and neighboring areas, serving stations including Hackney Central, Camden Road, and Hampstead Heath. The line historically developed between 1846 and 1869 as a cross-city connection avoiding central London and functions as a freight link between main lines. Modern operations feature reliable frequent service under Transport for London oversight since 2007, with the Class 378 fleet expanded to five-car formations.
Additional timetable layers bring in elements such as Class 710 units from the Suffragette line and Class 66 freight workings. AI traffic from routes like Southeastern High Speed and West Coast Main Line South appears at junctions, increasing operational density.
Is It Worth Playing?
This add-on suits players who enjoy precise train handling in a high-frequency commuter environment with realistic London scenery and integrated timetable operations. The combination of the detailed Class 378 cab, short station stops, and layered traffic creates a focused simulation experience. Route hopping expands possibilities for those who own compatible London routes. Newer core features from Train Sim World 7 may not apply to this compatible content. Availability requires the base game, and the 5.6 GB download delivers the route and train with support for custom scenarios and liveries.
