This Atlas Gold HO scale model represents a Phase I GE U30C locomotive of the Chessie System C&O #3301 in striking yellow, blue, and vermillion colors. The General Electric U30C, introduced in 1966, replaced the U28C and offered 200 more horsepower, competing with the EMD’s SD40. It was a best - seller in the Universal Series, selling 600 units in 10 years. This Phase 1 model has a constant - width long hood and unique radiator intake arrangements. Atlas also offers later Phase 2 and 3 models. Features include all - new tooling, etched metal grilles, various cab and light variations, newly tooled Adirondack truck sideframes, separately applied details, and factory - installed metal knuckle couplers. It comes in both DC and sound versions. The Gold Series with ESU sound has a decoder supporting all DCC programming modes, flexible function key mapping, and over 20 sound effects. Note on operation: The Atlas Quantum Engineer won't operate a Gold Series loco with a LokSound Select decoder on an analog layout, and on a DC - powered layout, DCC and sound locos have specific consist rules. Also, non - sound locos can't be MUed in DC mode due to the sound system's higher starting voltage.

Using this Atlas HO scale locomotive is a breeze. First, if you're using a DCC system, make sure it's set up correctly. You can easily control the locomotive's speed and direction using the DCC controller. For the sound functions, just press the relevant function keys on your controller to enjoy engine start - up, bell, horn, and other cool sound effects. If you're on an analog (DC) layout, remember that the Atlas Quantum Engineer won't work with the Gold Series loco having a LokSound Select decoder. And don't try to couple a DCC and sound - equipped locomotive with a non - DCC or non - sound one on a DC - powered layout. When it comes to maintenance, keep the locomotive clean. Use a soft, dry cloth to wipe off any dust. Check the wheels regularly for any debris that might affect its movement. Store it in a cool, dry place when not in use to prevent any damage to the delicate parts like the etched metal grilles and separately applied details.
