The huge railroad shop buildings dedicated to engine repairs were the heart and soul of the shop complex. The prototypes for the Cornerstone Railroad Shop were built for the needs of steam locos, but were easily upgraded to handle diesels in later years. Based on Walthers Cornerstone's earlier Backshop kit and sharing many architectural elements, this detailed structure kit is larger to handle almost any motive power. In addition to its many details, there's room on the inside for adding the Heavy-Duty Crane in the main bays, and the smaller Overhead Traveling Crane 933-3102, sold separately) in the annex. Used by itself, the Railroad Shop building is perfect for all kinds of heavy industries that require overhead crane space and a large working floor.
