The Athearn RND3195 HO Scale 3 Dome Tank Car set comes in a pack of four. These tank cars are a great addition to your model train collection. They feature a separately applied brake wheel, wireform safety handrails, and machined metal wheels with RP25 contours. The highly - detailed, injection - molded body is painted and printed realistically. The cars are weighted for optimum performance and are fully assembled and ready to run. The minimum radius for operation is 15 inches. The coupler style is McHenry Scale Knuckle, and it's recommended for users aged 14 and above. Tank cars are specialized railway equipment, with careful construction to ensure the compatibility of tank contents and the tank shell. In the rail industry, they're grouped by type rather than cargo carried, and those for chemicals or dangerous goods are made of different steels and have stronger tank heads.

Using these tank cars is easy. Since they're fully assembled, you can directly place them on your model train tracks with a minimum radius of 15 inches. Just connect them to your train using the McHenry Scale Knuckle couplers. When handling, be gentle with the wireform safety handrails and the separately applied brake wheel as they're delicate parts. For maintenance, keep the cars in a dry and clean place. You can use a soft brush to clean the dust off the body and wheels. Avoid using harsh chemicals on the painted and printed surfaces as it may damage the realistic decoration. Also, make sure to keep them out of reach of children under 14 years old.
