HO-scale Champlin/HHCX 1-dome tank car set, presented as a four-pack to help model longer tanker trains. Fully assembled and ready to run, these cars include decorated placards where appropriate, four unique road numbers, a separately applied brake wheel, and wire-form safety handrails for added realism.

With a highly detailed injection-molded body, machined metal wheels with RP25 contours, and body-mounted McHenry operating scale knuckle couplers, these cars offer dependable operation and realistic appearance. They are weighted for steady performance and designed for HO layouts with a minimum radius of 18 inches, making them a practical and authentic addition to a freight roster.
