HO 1-Dome Tank Union Starch/SHPX #1 Plastic Model (ATH3382)

HO-scale 1-Dome Tank Car for Union Starch/SHPX No. 1 is a fully assembled, ready-to-run model that brings a classic chemical tanker to your HO layout. The injection-molded plastic body faithfully recreates the prototype’s single-dome profile, making it an accessible, realistic addition for modeling longer trains and busy yard scenes.

Designed for dependable operation, it rides on machined metal wheels with RP25 contours and uses body-mounted McHenry operating scale knuckle couplers for solid coupling. The car is weighted for stable tracking and includes wireform safety handrails, a separately applied brake wheel, and decorative placards where appropriate. A minimum curve of 18 inches ensures smooth handling on typical layouts, and four-packs feature unique road numbers to help model longer consists. In prototype terms, tank cars are built with interior coatings to isolate contents from the shell and reinforced tank heads to withstand accidents, reflecting the careful engineering behind this specialized equipment used for chemicals and other cargos.
