The Atlas Gold 40005415 represents the FM H-24-66 Phase 1A Trainmaster of the Southern Pacific, numbered #4810, in N Scale. Note that the picture might show a different road number. Advertised by Fairbanks-Morse as 'the most useful locomotive ever built', the H24-66 Train Master made its debut in 1953. It's a versatile locomotive, suitable for both passenger and freight services across the US. At that time, it was the most powerful single - engine locomotive, boasting 2,400 hp. Key features include large number boards and a single headlight at the ends, golden - white LEDs, directional lighting, painted safety rails, etched metal grilles, blackened metal wheels, a scale speed motor, and factory - installed AccuMate® magnetic knuckle couplers. For Gold locomotives manufactured in 2022 or later, the DCC operation supports all programming modes, includes RailCom and RailComPlus, offers 14, 28 or 128 speed steps, and 2 - digit and 4 - digit addressing. Function keys F0 to F28 can be flexibly mapped, and there are 6 DCC function outputs that can be individually configured. It adheres to all NMRA DCC standards. The ESU LokSound in these locomotives provides over 20 sound effects, up to 16 user - selectable horns, 2 user - selectable bells, and 2 user - selectable synchronized brake squeals. It also offers manual and automatic notching modes that can be switched during operation for a realistic experience.

Using this locomotive is quite straightforward. First, make sure your DCC system is set up correctly according to the locomotive's DCC features. If you're using the sound functions, you can select different horns, bells, and other effects to suit your needs. When operating, you can switch between manual and automatic notching modes to mimic real - life locomotive behavior. For maintenance, keep the locomotive clean. Use a soft, dry cloth to wipe the body, and be careful around the delicate parts like the etched metal grilles. Check the metal wheels regularly for any signs of wear or dirt. If there's dirt on the wheels, you can gently clean them with a suitable cleaning agent. Also, follow the NMRA DCC standards when programming or operating the locomotive to ensure smooth performance. When not in use, store the locomotive in a cool, dry place to prevent damage.
