The Athearn ATH8391 3-pack of HO scale 52' Mill Gondola cars from the Rock Island (RI) line is a great addition to your model train collection. These cars come with body-mounted McHenry® operating scale knuckle couplers, making it easy to connect them in your train setup. The new 3-packs simplify the process of creating a complete train. They feature separately applied wire grab irons and etched end platforms, along with razor-sharp painting and printing for a realistic look. The cars are weighted for optimal performance and are fully assembled, so they're ready to go on your layout right away. The multi-packs have unique road numbers. With a minimum radius of 18 inches, they can fit well in various track designs. The primed for grime models replicate the look and feel of 'In Service' equipment, with faded base colors that match the prototype. They're also a perfect starting point if you want to add grime and rust for an even more realistic appearance. The coupler style is McHenry Scale Knuckle, and they're recommended for users aged 14 years and above. No assembly is required.

Using these Athearn HO scale gondola cars is a breeze. Just connect them to your train using the body-mounted McHenry® operating scale knuckle couplers. You can easily create a complete train with the 3-pack. Place them on your layout and enjoy watching them roll. As for maintenance, keep them clean. You can use a soft, dry cloth to wipe off any dust. If you want to add grime and rust to make them look more realistic, start with the primed models. Just use appropriate model paints and techniques. Remember, these cars are recommended for users aged 14 and above, so keep them away from younger kids. And since they're fully assembled, there's no need to worry about putting them together. Enjoy your model train experience with these great gondola cars!
