Designed as a HOn3 craftsman kit, the tank ends and hatch are accessories to the water car underframe kit. The iconic "Potable Water" tank car supplies the gypsum quarry at Split Mountain, some 26 miles away with drinking water from Plaster City. The tank can be constructed using 1/2" I.D. PVC pipe. Use the "HOn3 USG Trinity Water Car Tank Ends & Hatch" product to complete the tank structure. Please consult prototype photographs during the construction process. These kits are designed for moderate to advanced modellers that can supply some scratchbuilding skill and ingenuity to the build.
