The Atlas Gold 40005463 is a stunning N Scale model of the GE B23 - 7 locomotive from the Southern Railway, numbered #3977 in black and white color scheme. 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. The B23 - 7, with enhanced fuel efficiency, tractive effort, and reliability, replaced the 2,250HP U23B. It was first produced for Conrail in September 1977 and production lasted until 1984, with 535 units built. Conrail was the biggest buyer, with 141 units in its fleet. The B23 - 7 stands out with a long hood that steps out at the exhaust stack for an oil cooler, a 2 - foot longer frame than the U23B, and various truck types. It's powered by a 12 - cylinder GE FDL engine, indicated by six power assembly doors. 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 features like support for all programming modes, RailCom and RailComPlus, flexible function key mapping, and 6 function outputs. ESU LokSound features include over 20 sound effects, multiple user - selectable horns, bells, and brake squeals, and manual and automatic notching modes for realism.

Using this Atlas Gold N Scale GE B23 - 7 locomotive is easy. First, if you're using DCC operation, make sure your DCC system is set up correctly. You can use the various function keys to control lights, sounds, and other features. For sound, you can choose from different horns, bells, and other effects. When it comes to running the locomotive, place it on the track gently and start it up using your DCC controller. As for the speed, you can adjust it with the 14, 28, or 128 speed steps available. When not in use, store the locomotive in a dry and clean place. Avoid exposing it to extreme temperatures or humidity. For maintenance, you can use a soft brush to clean the locomotive and the wheels regularly. Check the couplers to make sure they're working properly. If you notice any issues with the DCC or sound functions, refer to the manufacturer's guide or contact customer support.
