This HO scale Atlas 20006296 FMC 5503 52-foot double-door boxcar is for Golden West Service #780021 in blue, yellow, and red. Note that the picture might show a different road number. In the past 50 years, box cars usually come in one of five frame lengths: 40, 50, 52, 60, and 86 feet. The 52-foot box cars are the least common. Despite being fewer in number compared to shorter and longer ones, they've played an important role in the lumber industry. This car is like a 'stretched' 5277 with an extra foot outside the bolsters, giving it a unique overhang. It has double sliding doors and a cushioned underframe. Southern Pacific was the original operator, ordering 700 of these distinct boxcars, split between Southern Pacific (525 cars), Amador Central (75 cars), and the Longview, Portland & Northern (100 cars). Key features include double sliding doors, wire grabs, etched parts, a Plate C box car design, and an X-Panel roof.

Using this HO scale boxcar is simple. Just place it on your model train track and let it roll. You can couple it with other train cars to create a longer train. When handling the car, be gentle to avoid damaging the wire grabs and etched parts. To keep it in good condition, clean it regularly with a soft, dry cloth. Avoid using any harsh chemicals or abrasive materials as they can scratch the paint or damage the details. Store it in a cool, dry place away from direct sunlight to prevent the colors from fading. If you notice any loose parts, you can use a small amount of glue to fix them, but make sure to use a glue that is suitable for model trains.
