The ATLAS Master 20006966 is a high - quality HO scale 20,700 gallon tank car representing Eastman Chemical, with the GATX number 99551 in black, white, and yellow. Note that the picture might show a different road number. In the mid - Sixties, General American Transportation Corporation (GATX) introduced the 20,700 gallon tank car design that this Atlas model recreates. It's a general - purpose, non - insulated, non - pressure tank car. The model comes with two major saddle variations (Type 10 and Type 20) and two top platform options (one - and two - piece). This tank car typically carried common products like tallow, animal fat, fuel oil, diesel fuel, vegetable oil, soybean oil, fertilizers, lubricating oil, waste oil, and glycol. Key features include a detailed five - section non - insulated body, two saddle choices, a detailed top platform with two options, A - end pipe stubs (where applicable), see - through end walks, detailed brake gear and pipes, a bottom outlet, a safety vent, a manway, a control housing, a stuffing box, safety rails, and accurate lettering that matches the prototype cars.

Using this ATLAS HO scale tank car is easy. Just place it on your model train track as part of your train set. When handling it, be gentle to avoid any damage to the detailed parts. Keep it away from rough surfaces or sharp objects. For maintenance, use a soft, dry cloth to wipe off any dust regularly. If there are stubborn stains, you can use a very mild soap solution and a soft brush, but make sure to dry it thoroughly afterward. Don't expose it to extreme temperatures or humidity as this can cause the colors to fade or the parts to warp. Check the wheels periodically to ensure they rotate smoothly. If they seem stuck, clean them gently with a cotton swab. That's all you need to do to keep your tank car in great shape and enjoy it for a long time.
