The Athearn ATH90574 60' DD/SS High Cube Plug Boxcar in HO Scale, representing Norfolk Southern #620022, is a remarkable model. The PRIMED FOR GRIME MODELS feature an 'In Service' look, with faded base colors like the real thing. It's a great start for adding grime and rust. The model has double 8' Youngstown doors, a photo-etched coupler cross-over platform, and separately applied grab irons, end ladders, and brake wheel. It's fully-assembled and ready to run right out of the box. With a highly-detailed, injection-molded body, it's painted and printed realistically. It's weighted for smooth operation and comes with body-mounted McHenry operating scale knuckle couplers. The 70 or -100 ton roller bearing trucks have 33' or 36' wheels as per the prototype, and machined metal wheels with RP25 contours. The minimum radius is 18'. The coupler style is McHenry Scale Knuckle, recommended for ages 14 and up, and no assembly is required.

Using this Athearn boxcar is easy. Just take it out of the box and it's ready to run on your HO scale track. When setting it up on the track, make sure the couplers are properly aligned to connect with other cars. As for the minimum radius of 18', ensure your track layout meets this requirement for smooth operation. Since it's already weighted, you don't need to worry about balance issues. For maintenance, keep it clean from dust and debris. You can use a soft brush to gently clean the body and wheels. If you want to add more grime and rust for a more realistic look, use appropriate model paints and techniques. Always store it in a dry place to prevent any damage. And remember, it's recommended for users aged 14 and up, so make sure younger kids are supervised if they're around it.
