The Atlas Gold 40005460 N Scale locomotive represents the GE B23 - 7 ATSF Santa Fe #6402 in Warbonnet blue and yellow livery. Note that the picture might show a different road number. General Electric's 'Dash 7' locomotives replaced the older 'Universal - Series' from the 60s and early 70s. They offered better fuel efficiency, tractive effort, and reliability. The B23 - 7 replaced the 2,250HP U23B. Production started in September 1977 for Conrail and lasted until 1984, with 535 units built. Conrail bought the most, with 141 units. The B23 - 7 has unique features. Its long hood steps out by the exhaust stack for an oil cooler, and the frame is 2 feet longer than the U23B's. It comes with an FB - 2 style truck as standard, but some models have AAR type B or Blomberg trucks. The six power assembly doors near the long - hood center mean it has a 12 - cylinder GE FDL engine. Key features include directional lighting with golden - white LEDs, dual brass flywheels, a low - friction mechanism, accurate painting and lettering, and factory - installed AccuMate® magnetic knuckle couplers. Gold locomotives offer great DCC operation, supporting all programming modes, RailCom and RailComPlus, with flexible function key mapping. There are 6 DCC function outputs. They also have ESU LokSound with over 20 sound effects, multiple user - selectable horns and bells, and realistic notching modes.

Using this N Scale Atlas Gold locomotive is easy. First, make sure your DCC system is set up correctly. If you're new to DCC, start with the basic programming mode. The locomotive supports all DCC - programming modes, so you can choose the one that suits you best. When it comes to the sound, you can select from over 20 sound effects to add realism to your model railway. To change the sound settings, use the function keys on your DCC controller. The flexible mapping of function keys F0 to F28 allows you to customize the controls. For maintenance, keep the locomotive clean. You can use a soft brush to remove dust from the body and wheels. Avoid using harsh chemicals as they might damage the paint or the mechanism. Check the couplers regularly to ensure they're working properly. If the locomotive seems to be running rough, it might be a good idea to lubricate the moving parts, but use a small amount of lubricant designed for model trains. Remember, the picture might show a different road number, so don't be surprised if the actual locomotive looks a bit different from what you see in the image.
