There are few shops capable of replicating a full size, standard gauge steam locomotive to exacting historic specifications.  The Lyon project is unique in North America due to its strict adherence to the original Union Iron Works design, which has required intensive research by our engineering staff.  The original Lyon was out of service and in derelict condition, circa 1890.  She was scrapped shortly afterward.  There are no known photos of this locomotive taken when she was still intact.  All design work was based on  one surviving erection drawing, and five photographs showing the engine partially dismantled in the scrapyard.  Here a completed rolling running gear with the boiler.
