The Atlas Gold 40005457 presents a remarkable N Scale model of the GE B23 - 7 Minnesota Commercial Locomotive #44, featuring red and white ditch lights, along with DCC and sound capabilities. Note that the picture might show a different road number. General Electric's 'Dash 7' locomotive series came as a replacement for the older 'Universal - Series' from the 60s and early 70s. It boasted enhanced fuel efficiency, tractive effort, and reliability. The B23 - 7 directly replaced the 2,250HP U23B. First produced for Conrail in September 1977, production lasted until 1984, with 535 units built. Conrail was its biggest buyer, owning 141 units. The B23 - 7 had unique features. Its long hood stepped out near the exhaust stack for a relocated oil cooler, and its frame was 2 feet longer than the U23B's. It usually came with an FB - 2 style truck, but some railroads used 'trade - in' trucks, so you might find AAR type B or Blomberg trucks on some models. The six power assembly doors near the long - hood center indicate it's powered by 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. For gold locomotives, the DCC operation supports all programming modes, includes RailCom and RailComPlus with various speed steps and addressing options, has flexible function - key mapping, 6 function outputs, and follows NMRA DCC standards. The ESU LokSound offers over 20 sound effects, multiple user - selectable horns, bells, and brake squeals, and both manual and automatic notching modes for a realistic experience.

Using your Atlas Gold N Scale GE B23 - 7 locomotive is easy. First, make sure your DCC system is set up properly. Connect the locomotive to the track and power on the system. You can start programming the locomotive using the DCC controller. Select the appropriate address and start adjusting the speed and functions. For sound, use the function keys on your controller to activate different sound effects like the bell or the air horn. When it comes to maintenance, keep the locomotive clean. Use a soft brush to remove dust from the body and wheels. Check the couplers regularly to ensure they're working properly. If you notice any issues with the DCC or sound functions, refer to the user manual or contact customer support. Also, store the locomotive in a dry and cool place to prevent any damage. Remember, this is a delicate model, so handle it with care to enjoy it for a long time.
