HO 13K Gallon Acid Tank Car ASTX #5031 (ATHG-1440)

HO scale 13,000-gallon acid tank car ASTX 5031 is a meticulously detailed model designed to bring realism to HO railroading. It faithfully represents two body phases—early and late—with period-correct top platforms and other prototype-specific details, making it a convincing addition to industrial-era or modern freight trains.

Its construction emphasizes authentic operation and durability: etched metal walkways, separate wire grabs and handrails, and trucks with animated rotating bearing caps. It uses body-mounted McHenry scale double-shelf knuckle couplers and a fully detailed underframe with air brake reservoir, control valve, brake cylinder with plumbing and brake rods. A wide array of individually applied details, including end sills, coupler lift bars, trainline hoses, and brake hoses, adds to the model's realism. Machined metal wheels with RP25 contours roll smoothly on most track brands, and the car is designed for an 18-inch minimum radius, making it compatible with common HO layouts.
