# Train Simulator: D&RGW SD50 Loco Add\-On Summer DB entity ID: c63e56ee\-94a7\-4440\-98b1\-53913031da3a Steam App ID: 325955 Electro\-Motive Division’s powerful SD50 comes to Train Simulator from Digital Train Model\. The SD50 from General Motors Electro\-Motive Division was produced to counter increasingly tough competition from GE Transportation Systems’ Dash 7 line, which was proving to be successful with US railroads\. Whilst EMD’s SD40\-2 was more reliable, GE’s line included locomotives up to 3,600hp \(2,685kW\) with more modern technology\. EMD’s had already established a track record for producing 3,600hp locomotives, with the SD45 and SD45\-2; however, demand for these gas guzzlers dropped sharply after the 1970s fuel crises\. The SD50 was heavily updated, with a new V16 engine uprated with more horsepower\. Unfortunately, this proved to be an unsuccessful move as the 50 series models were plagued by engine and electrical system problems\. The SD50’s long hood saw changes from previous EMD models; the overall frame length was increased, and the long hood was made substantially longer\. Resistors for the dynamic brake grid were also moved to a new, cooler location in front of the engine compartment air intakes, thereby simplifying the prime mover maintenance procedures, and the electrical system as well\. The EMD SD50 for Train Simulator, developed by Digital Train Model, is available in Denver & Rio Grande Western Railroad livery and features engine start/stop, dynamic brakes, front and rear headlights, numberboard lights, class lights and step lights\. The locomotive is also Quick Drive compatible, giving you the freedom to drive the D&RGW SD50 on any Quick Drive enabled route for Train Simulator, such as those available through Steam\. Also included are scenarios specifically for the Soldier Summit route \(available separately and required to play these scenarios\)\. Scenarios Four scenarios for the Soldier Summit route: Industrial Operation Green River Higher Priority The Storm and the Rock Slide More scenarios are available on Steam Workshop online and in\-game\. Train Simulator’s Steam Workshop scenarios are free and easy to download, adding many more hours of exciting gameplay\. With scenarios being added daily, why don’t you check it out now\!
