Bring oil industry traffic to your HO Scale railroad with the Walthers Cornerstone United Petroleum Refining oil refinery kit. Railroads are vital to refinery operations, from the switchers that move cars, to the mainline freights that hustle finished products to market. This kit has been carefully designed to capture the realism of a prototype oil refinery in a size that works on most layouts. The superdetailed kit includes a main fractionating tower, furnace, piping group and heat exchangers, vacuum pipe still and decal warning signs. Additional piping, safety caged ladders, platforms and photo-etched brass handrails are also included to make your model more realistic.
