This detailed Atlas HO Scale Master Silver EMD SD24 is based on the 2,400-horsepower diesel road units produced by EMD between July 1958 and March 1963. The Atlas model features details and high or low nose unique to each roadname. Other features include a five-pole skewed-armature motor with dual flywheels, directional LED lighting, all-metal magnetic knuckle couplers, accurate decoration and roadname-appropriate body phase details. Plenty of applied details and realistic decoration for both prototype and fantasy "what if" schemes round out the detailed models. The sound-ready EMD SD24 comes equipped with a factory-installed speaker and DCC socket for easy decoder installation when you're ready. This EMD SD24 is one of many Atlas and Trainman HO Scale locomotives.
