Train Sim World 7: ScotRail BR Class 158 Sprinter DMU Add-On is a rail simulation experience for PC that places players in the cab of a distinctive diesel multiple unit. This add-on brings the ScotRail variant of the BR Class 158 to existing Scottish routes, emphasizing realistic operations on inter-city and regional lines out of Edinburgh and Glasgow.
Gameplay
The core loop centers on operating the Class 158 Sprinter with attention to its real-world characteristics. The unit reaches a top speed of 90 mph on longer stretches between Edinburgh and Glasgow Queen Street, requiring precise throttle and brake management to maintain schedules while respecting speed limits and signals. ScotRail-specific details include altered headlights, an integrated snowplough, a revised cab layout, and changes to the passenger interior such as updated seating and luggage areas. These elements affect visibility, handling in varied weather, and the overall driving feel compared to other variants of the same train type.
Performance modeling follows the train's late-1980s design origins, with emphasis on sound insulation and regional express duties. Players handle coupling with compatible units like the Class 170 for mixed formations, particularly on Fife Circle operations. A training center tutorial introduces the controls and systems before moving to full services. The add-on supports livery customization and scenario creation tools for extended play.
Game Modes
Scenarios provide structured sessions with specific objectives on the Edinburgh-Glasgow and Fife Circle Line routes. Three scenarios are available for each route, covering timetable duties and additional tasks that highlight the Class 158's capabilities in Scottish Lowlands conditions.
The Express Sprinter timetable expands playable services across the ScotRail Express: Edinburgh-Glasgow route. It includes dozens of Class 158 runs alongside other traction, creating a full day of operations with AI traffic. Players select services and follow real-time scheduling demands.
Free Roam allows unrestricted exploration of the routes with the Class 158. Users spawn the train at chosen locations, experiment with formations, and run ad-hoc journeys without timetable constraints. This mode also supports the add-on's compatibility with scenario planning tools.
Route Integration and Operations
The Class 158 integrates directly with the Edinburgh-Glasgow and Fife Circle Line add-ons. Services depart from Glasgow Queen Street and connect across the Firth of Forth, often working alongside Class 170 and Class 385 units. The new timetable layers additional Class 158 duties onto existing infrastructure, increasing variety for owners of those routes. Players manage passenger flows, depot movements, and express runs that showcase the train's longer body profile and 2+2 seating configuration in a simulated environment.
Modern ScotRail modifications appear through updated modeling, reflecting years of fleet updates while preserving the original Sprinter traits. Operations remain focused on regional services that have become less common due to electrification but continue in key corridors out of major Scottish cities.
Is It Worth Playing?
This add-on suits players who already own the ScotRail Express: Edinburgh-Glasgow or Fife Circle Line routes and seek more variety with a detailed diesel unit. It delivers targeted ScotRail modeling, a dedicated timetable, and scenario content that expands daily operations without requiring new base routes. Reception in community discussions notes strong attention to cab and interior differences from the East Midlands version, along with functional timetable additions that improve replay on supported lines. Those interested in realistic DMU handling and Scottish rail services will find consistent value in the focused content. Newer players may prefer starting with core routes before adding this pack, as full enjoyment depends on the supporting infrastructure.
