Passenger Car Washer Walthers Part # 933-3186 HO scale, $19.98, not currently in stock at Walthers, Expected: 17-Nov-2004 With growing competition from airlines and highways after World War II, railroads had to be at their best to attract and keep riders. In addition to new streamlined trains, many upgraded service facilities to speed operations and reduce costs. One of the major changes at many coach yards was the addition of a car washer. These mechanical wonders eliminated most of the hand scrubbing so that entire trains could be washed from engine to observation in a matter of minutes. This all-new kit is based on the six-brush washers favored by many roads. Large brushes, simulated motor drives, sprayer and rinse nozzles, a washer control house and a detailed base plate with drains are all included. Base measures 5-1/2 x 3-1/2 x 2-5/8" 13.7 x 8.7 x 6.5cm; Control House measures 1-1/8 x 1-1/8 x 1-7/8" 2.8 x 2.8 x 4.6cm.
