HO 13K Gallon Acid Tank Car RPBX Model (ATHG-1437)

HO Scale 13,000-Gallon Acid Tank Car, RPBX Model. This HO-scale model faithfully represents the RPBX prototype’s 13,000-gallon acid car, delivering an authentic addition to an operating layout or display roster. Designed for use on standard HO track, it pairs well with other RPBX cars to recreate realistic chemical traffic on a busy line.

Key details include two body-phase variations (early and late), prototype-appropriate top platforms, separate wire grabs and handrails, and trucks with animated rotating bearing caps. The car rides on machined metal wheels with RP25 contours and uses body-mounted, scale double-shelf knuckle couplers for reliable operation. A fully detailed underframe features an air-brake reservoir, control valve, and brake cylinder plumbing, while etched walkways, varied brake systems, end sills, coupler lift bars, trainline hoses, and brake hoses add authentic richness with many separately applied details. With an 18-inch minimum-radius requirement, it’s compatible with a wide range of HO layouts, and multiple road numbers across singles or a three-car set provide roster variety.
