Introducing the Atlas Gold 40005452 GE B23 - 7 locomotive in N scale, Conrail #1948, featuring ditch lights in blue, white, and a white sill. It comes with DCC & Sound functionality. Note that the picture might show a different road number. General Electric's 'Dash 7' locomotives replaced the older 'Universal - Series' of the 60s and 70s. The B23 - 7, a replacement for the U23B, had better fuel efficiency, tractive effort, and reliability. Conrail was its biggest buyer, getting 141 units from 1977 to 1984. The B23 - 7 has unique features like a stepped long hood for an oil cooler, a 2 - foot longer frame than the U23B, and different types of trucks. It's powered by a 12 - cylinder GE FDL engine. This model has 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, including RailCom and RailComPlus. They have flexible function key mapping and 6 function outputs. 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 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 use the DCC controller to control the speed and direction of the locomotive. The directional lighting will automatically change based on the direction of movement. For the sound features, you can select different sound effects using the function keys on your DCC controller. There are many sound options like engine start - up, horn, and bell. When it comes to maintenance, keep the locomotive clean. You can use a soft, dry cloth to wipe off dust from the body and wheels. Avoid using harsh chemicals as they might damage the paint and lettering. Also, check the couplers regularly to ensure they are working properly. If you notice any issues with the DCC or sound functions, make sure to check the connections first. If the problem persists, contact the manufacturer's customer support.
