The Boston and Maine/Maine Central Mountain Division is designed for operation. It is loosely based on the B&M’s Conway branch and the MEC’s climb through Crawford Notch, both in New Hampshire, during the post WW II era when railroads were transitioning from steam power to diesel. It is a singletrack railroad 400 feet in length with passing sidings in each town, serving 30 industries. Portions are double-decked. North Conway provides an interchange between the two railroads. Bartlett is the base for helpers needed to assist trains through Crawford Notch. Scott Paper Company is the major industry, requiring its own switcher. NCE DCC powers the railroad. Operation uses seven people, train cards, four-part waybills and radios but without a dispatcher. Staging loops at each end allow rapid turning of entire trains.
