This HO scale model is the Atlas 10003152 ALCO RS-1 representing Milwaukee Road #873. It comes in an eye - catching orange and black color scheme with the TMR Logo on the cab. Note that the picture might show a different road number. The RS - 1, introduced by ALCO in March 1941, was a game - changer in locomotive design. It combined the best of switching locomotives and road units. Despite ALCO launching higher - horsepower models later, the 1,000 h.p. RS - 1 was produced for 19 years with 623 units made. Key features include a retooled die - cast metal chassis, fine - scale handrails, Golden White LEDs, and a LokSound decoder in the DCC/Sound version. It also has separately - applied wire grab irons, accurate painting and printing, and AccuMate® couplers. The five - pole skewed armature motor with dual - flywheels ensures great performance at all speeds. For sound features in the Gold Series, it supports all DCC - programming modes, has flexible function key mapping, and offers over 20 sound effects. The LokSound Select Dual - Mode decoder allows use on both DC and DCC layouts, but there are some operating limitations to be aware of.

Using your Atlas 10003152 ALCO RS - 1 locomotive model is easy. First, if you're using it on a DCC layout, make sure your system is compatible with the DCC/Sound features. You can control the locomotive's movement, lighting, and sound functions easily through the DCC system. If you want to use it on a DC layout, the LokSound Select Dual - Mode decoder allows that, but remember the Atlas Quantum Engineer won't work on an analog (DC) layout. Also, on a DC - powered layout, you can't run it with a locomotive that doesn't have both DCC and sound. When it comes to maintenance, keep it clean. You can use a soft, dry cloth to wipe off any dust. Check the wheels and axles regularly to make sure they're moving smoothly. If you notice any loose parts like the wire grab irons or coupler cut bars, you can gently re - attach them. Store the locomotive in a cool, dry place to avoid any damage to the paint or the internal components. Have fun with your model!
