The Atlas Gold 40005372 N Scale model train is an EMD GP9 locomotive with torpedo tubes, representing TH&B Toronto Hamilton & Buffalo #402. The picture might show a different road number. Introduced in 1949, the Electro - Motive 1500hp GP - 7 combined F7 machinery with a hood - type carbody for high visibility and easy engine access. It could pull all kinds of trains and sometimes replace cab units. The GP - 9, with a 1750hp engine, looks similar to the GP - 7. Key features include a powered low - friction drive, blackened metal wheels, dual brass flywheels, directional lighting with golden - white LEDs, and AccuMate® couplers. Gold locomotives offer great DCC operation, supporting all programming modes, including RailCom and RailComPlus. They have flexible function key mapping and follow NMRA standards. The ESU LokSound provides over 20 sound effects, multiple user - selectable horns, bells, and brake squeals, along with manual and automatic notching modes for a realistic experience.

Using this model train is easy. First, make sure your DCC system is set up correctly. You can start programming the locomotive following the DCC - programming modes it supports. To enjoy the sound features, turn on the power and use the function keys to access different sound effects like the engine start - up, bell, or air horn. When it comes to running the train, the low - friction drive and flywheels will help it move smoothly. For maintenance, keep the metal wheels clean to ensure good electrical contact. You can use a soft brush to gently remove any dust or debris. Avoid exposing the train to extreme temperatures or moisture, as this could damage the electronics. If you want to change the sound settings or function mappings, refer to the DCC and ESU LokSound documentation. With proper care, this model train will provide you with a long - lasting and enjoyable experience.
