HO 13,600-Gallon Acid Tank by PROX (ATHG25762)

HO-scale 13,600-gallon acid tank car from PROX, designed for realistic freight on HO layouts. This model, finished in white, recreates a real industrial tanker to add authentic detail to tank-car scenes on a model railroad.

Key features include multiple road numbers with variations across singles and three-packs, a wealth of separately applied details, etched metal walkways, and prototype-appropriate end sills and brake systems. The model also includes separate wire grabs and handrails, trucks with animated rotating bearing caps, and body-mounted McHenry scale double-shelf knuckle couplers for authentic operation. Underframe details capture the air-brake reservoir, control valve, and brake cylinder with plumbing and brake-rod details, while machined metal wheels with RP25 contours deliver smooth performance on most HO tracks. Trainline hoses, brake hoses, and other hardware are included, and the finish is carefully painted and printed for prototypical realism. It negotiates HO curves with a minimum radius of 18 inches, making it a versatile addition to industrial and mainline freight consists.
