The Atlas 20006554 is an HO scale PS-2 covered hopper model train car, specifically representing Penn Central #74216 in green and white. Note that the picture might show a different road number. Covered hoppers are a modern addition to the train car family. Until the 1980s, the AAR regarded them as “special” cars, and then they got their own car - type code. These early designs were mainly for efficient cement loading and unloading, replacing the old method of bagging cement and using box cars. Pullman - Standard started building this two - bay covered hopper design in the late 1940s, with production lasting into the 1950s. It has eight round roof hatches for fast loading and two large gravity gates for quick commodity discharge, with a capacity of 2,003 cubic feet. Key features include 50 - ton friction bearing or 70 - ton roller bearing trucks (depending on the road name), detailed brake gear, Accumate® couplers, and prototypical painting and printing.

Using this Atlas HO scale covered hopper model train car is easy. Just connect it to your train set using the Accumate® couplers. You can use it in your model train layout to create a realistic look. When handling the car, be gentle to avoid damaging the detailed brake gear and other components. To keep it in good condition, store it in a dry and dust - free place. If it gets dirty, you can use a soft, dry cloth to clean the body. Don't use any harsh chemicals as they might damage the prototypical painting and printing. Also, make sure to check the trucks regularly to ensure they roll smoothly. If you're using it with a train set that has different weight requirements, choose the appropriate 50 - ton friction bearing or 70 - ton roller bearing trucks according to the road name.
