Train Sim World 7: New Journeys - S-Bahn Köln BR 423 Add-On is a simulation title for PC that adds the DB BR 423 electric multiple unit to the existing Schnellfahrstrecke Köln - Aachen route. Players take control of this four-car EMU in its distinctive red S-Bahn Köln livery to handle commuter passenger services. The add-on focuses on high-density operations around Cologne, with services extending to Horrem and Düren. It requires the separate Schnellfahrstrecke Köln - Aachen Remastered route add-on to function.
Gameplay
The core loop centers on realistic train operation using the proprietary SimuGraph vehicle dynamics engine. Drivers manage acceleration, braking, and speed limits while following signals and timetables on the busy corridor that mixes S-Bahn, regional, and ICE traffic. The DB BR 423 features a highly detailed cab with authentic controls and true-to-life handling characteristics. Day and night cycles bring continuous activity, with dozens of units operating simultaneously on the network. The add-on includes three hand-crafted scenarios that place the BR 423 in specific operational situations on the route.
Performance modeling emphasizes accurate response to gradients, load, and track conditions typical of the Köln to Aachen line. Players must account for station stops, door operations where applicable, and integration with other services. The content supports the Livery Designer and Formation Designer tools for custom appearances and consists, along with the Scenario Planner for creating additional runs.
Game Modes
Scenarios provide structured experiences with objectives and guidance, delivering three detailed outings focused on the BR 423. Timetable mode introduces a dedicated schedule layer that places the unit on S19 and new S12 services, allowing players to complete full shifts ferrying passengers through the cathedral city and onward to the western endpoints. This layer also integrates into the remastered route's overall timetable for broader operations.
Free Roam supports ad-hoc exploration of the route with the new train, while the Creators Club compatibility enables sharing of custom liveries and formations. The add-on does not introduce entirely new core modes beyond these timetable and scenario enhancements.
Route and Train Details
The Schnellfahrstrecke Köln - Aachen forms the backbone, featuring high-speed sections alongside dense urban and suburban stops. The BR 423 operates primarily on shorter commuter legs but shares tracks with faster long-distance trains, requiring careful timing and adherence to signaling. Night services add variety through reduced visibility and different traffic patterns. The unit's compact size suits the frequent stops and tight schedules of S-Bahn duties.
Is It Worth Playing?
This add-on suits players who already own the Köln - Aachen route and seek additional variety in S-Bahn passenger duties. It delivers a focused expansion centered on one specific EMU and an expanded timetable layer rather than a full new route. Those who enjoy precise cab controls, scheduled services, and mixing with other traffic will find the content aligns with that preference. The three scenarios and new timetable services provide immediate playable content without requiring further purchases beyond the required base route. Compatibility with design tools extends replay value for creators. Overall, it serves as a targeted addition for simulation enthusiasts focused on German commuter operations.
