The Atlas Gold 40005471 presents the GE B30 - 7 SP Southern Pacific #7850 in N Scale, equipped with DCC & Sound. It features ditch lights in red and gray, along with speed lettering. 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. These models offer better fuel efficiency, tractive effort, and reliability. The B23 - 7 replaced the 2,250HP U23B. It was first made for Conrail in September 1977 and production lasted until 1984, with 535 units built. Conrail bought the most, with 141 units. The B23 - 7 has distinct features. Its long hood steps out by the exhaust stack for a relocated oil cooler, and its frame is 2 feet longer than the U23B. It usually comes with an FB - 2 style truck, but some models may have AAR type B or Blomberg trucks. The six power assembly doors near the long - hood center show it's powered by a 12 - cylinder GE FDL engine. Key features include directional lighting, golden - white LEDs, dual brass flywheels, a low - friction mechanism, accurate painting and lettering, and factory - installed AccuMate® magnetic knuckle couplers. For gold locomotives, DCC operation supports all programming modes, includes RailCom and RailComPlus with various speed steps and addressing options, has flexible function - key mapping, and 6 individually - mappable function outputs, following NMRA DCC standards. ESU LokSound offers over 20 sound effects, up to 16 user - selectable horns, 2 user - selectable bells, and 2 user - selectable synchronized brake squeals, along with manual and automatic notching modes for realism.

Using your Atlas Gold N Scale GE B30 - 7 locomotive is easy. First, make sure your DCC system is set up correctly. You can then power on the locomotive and start operating it. Use the DCC controller to adjust the speed and control the various functions like lights, horn, and bell. For the sound effects, just select your preferred options on the ESU LokSound system. When it comes to maintenance, keep the locomotive clean. You can use a soft brush to remove dust from the body and wheels. Check the couplers regularly to ensure they are working properly. If you notice any issues with the DCC or sound functions, refer to the manufacturer's manual or contact customer support. Also, store the locomotive in a dry and cool place to prevent any damage. Avoid exposing it to extreme temperatures or humidity.
