Bench tested on rollers. Ran well. Quite and smooth. Over all excellent condition. The Overland OMI-6052 AT&SF SD45 #5344 HO F/P W/Smoke Deflectors & Air Intake Hoods is a highly detailed replica of a AT&SF SD45 diesel locomotive in 1:87 scale. Made of brass and featuring factory paint, this ready-to-go model is equipped with smoke deflectors and air intake hoods for added realism. With an analog control system and designed for 2-rail-2-conductor rail systems, this locomotive is a great addition to any HO scale model railroad collection, especially for fans of the AT&SF corporate roadname.
