The ATLAS Master 20006979 is a 20,700-gallon HO scale tank car representing UP Union Pacific #903025, with blue, red, white, and black colors. It's a scale test car, and the picture might show a different road number. In the mid-Sixties, General American Transportation Corporation (GATX) introduced this tank car design. It's a general - purpose, non - insulated, non - pressure tank car. The Atlas model recreates two saddle variations (Type 10 and Type 20) and two top platform options (one - and two - piece). Common products carried include tallow, animal fat, fuel oil, and more. Key features are a detailed five - section non - insulated body, multiple saddle and platform choices, see - through end walks, and accurate lettering to prototype cars.

Using this HO scale tank car is simple. 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 like the brake gear and pipes. For maintenance, use a soft, dry cloth to clean the body and remove any dust. Don't use harsh chemicals as they might damage the paint. Store it in a cool, dry place away from direct sunlight to prevent color fading. If you notice any loose parts, you can use a small amount of glue suitable for model trains to fix them, but make sure to follow the glue's instructions.
