Bring oil industry traffic to your railroad with the Walthers Cornerstone North Island 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 kit includes a main fractionating tower, furnace, piping group and heat exchangers, vacuum pipe still and decal warning signs.
