The Atlas 10003925 is a fantastic HO scale model of the GE U30C Phase I locomotive from the Seaboard Coast Line, numbered #2124 in black and yellow gold. It comes with DCC and sound features (the picture might show a different road number). The General Electric U30C, launched in 1966, replaced the U28C. With 200 more horsepower than its predecessor, it let GE compete with EMD’s SD40. It was very popular, selling 600 units in 10 years, making it the best - selling Universal Series GE locomotive. This Atlas model represents a Phase 1 U30C, with a constant - width long hood and unique radiator intake arrangements. Atlas also offers later Phase 2 and 3 models. Key features include all - new tooling, etched metal grilles, various cab and light variations, newly tooled Adirondack truck sideframes, separately applied details, factory - installed metal knuckle couplers, and both DC and sound versions. Gold Series models with ESU sound have an ESU LokSound decoder, flexible function key mapping, and over 20 sound effects. DCC operation supports all programming modes, has flexible function key mapping, and six function outputs. Remember, on an analog (DC) layout, the Atlas Quantum Engineer won't operate a Gold Series locomotive with a LokSound Select decoder, and a DCC - sound locomotive can't be coupled with a non - DCC - sound one. Also, due to the sound system's higher starting voltage, you can't MU a non - sound loco in DC mode.

Using this Atlas HO scale locomotive is easy. If you're using a DCC layout, the locomotive supports all DCC - programming modes, so you can set it up according to your preferences. Just connect it to your DCC system and start operating. For analog (DC) operation, keep in mind that the Atlas Quantum Engineer won't work with a Gold Series locomotive having a LokSound Select decoder. Also, you can't couple a DCC - and - sound - equipped locomotive with a non - DCC - and - non - sound one on a DC - powered layout. When it comes to maintenance, keep the locomotive clean. You can use a soft brush to remove dust from the body, wheels, and other parts. Check the metal knuckle couplers regularly to make sure they're in good working condition. If you notice any issues with the sound or lighting functions, first check the connections in your system. Store the locomotive in a dry place to prevent any damage from moisture.
