Train Sim World 2: BR Class 31 Loco Add-On delivers a focused train simulation experience centered on the British Railways Class 31 diesel locomotive. This add-on brings the Type 2 locomotive from the 1950s modernization era into the Tees Valley Line route, allowing players to operate it in its classic BR Corporate Blue livery alongside the included PCA Cement Tank Wagon. The simulation emphasizes accurate vehicle dynamics through the SimuGraph engine, with true-to-life performance characteristics suited to secondary passenger and lighter freight duties.
Gameplay
The core loop revolves around operating the BR Class 31 diesel electric locomotive with realistic handling that reflects its historical power output and tendency to slip under load. Players manage throttle, braking, and multiple-working setups while navigating the Tees Valley Line. Detailed cab interiors include authentic controls and headcode displays, and the sound design draws from recordings of actual locomotives to capture the diesel engine characteristics. The included PCA Cement Tank Wagon integrates into freight operations, supporting shunting tasks and junction management that match the locomotive's role in lighter traffic.
Performance modeling accounts for the locomotive's design as a 1000-1499 horsepower Type 2 unit, making it suitable for paired operation on freight trains. Players experience the transition from steam to diesel traction through precise simulation of boiler systems and compatibility features from the 31/1 subclass.
Game Modes
The add-on supports scenario-based play with three dedicated scenarios set on the Tees Valley Line. These range from introductory sessions focused on shunting wagons and manual junction operation to more involved duties that put the Class 31 through its paces on passenger and freight runs. An interactive training session provides guided practice with the locomotive's controls and systems.
Timetable mode integrates the BR Class 31 into scheduled services on the Tees Valley Line, adding extra timetabled trains that increase overall route traffic. This mode emphasizes long-form operation where players follow real-world style schedules while managing the locomotive's limitations on secondary duties.
Route and Historical Context
The Tees Valley Line serves as the primary setting, recreating operations from Thornaby Depot and surrounding areas where the Class 31 fleet handled diverse traffic. The locomotive appears in its standard configuration with steam heating boilers and multiple-working capability, reflecting its widespread use across British Railways regions after the initial Eastern Region deployments.
Historical accuracy extends to the fleet's evolution, including subclasses developed as technology advanced, though the add-on centers on the reliable 31/1 variant that formed the backbone of many secondary services.
Is It Worth Playing?
This add-on suits players who seek detailed locomotive simulation within an established train sim framework. The combination of authentic sounds, precise handling, and expanded timetable services on the Tees Valley Line provides meaningful content for those interested in British diesel traction from the modernization period. It integrates seamlessly into existing route operations without requiring additional purchases beyond the base game and route.
Reception highlights the quality of the rolling stock and sound implementation, with the scenarios offering structured progression from basic controls to operational challenges. For simulation enthusiasts focused on realistic freight and passenger duties, the package delivers consistent value through its verified features and route integration.
