Don your work boots and gloves before getting inside looks of No. 261 getting a complete overhaul. Follow the cameras into the cavernous chambers of the firebox and boiler for incredible action on how this steam locomotive was rebuilt. You will get engrossing details on circulators, superheaters, dry pipes, injectors, grates, valve gear, the cylinders and stroker. The operation of these parts is explained, often by the men doing the restoration. This is a great production that educates as it fascinates! Running time: 1 hour 55 minutes.
