DOUBLE-HEADING BERKSHIRES IN WEST VIRGINIA
The 2-8-4 wheel arrangement, developed by the Lima Locomotive Works of Ohio in 1925, heralded the age of the "Super-power" steam locomotive.  With a large firebox and high steam capacity boiler, it could move heavy freight trains at sustained speeds of 70 miles-per-hour.   Two are currently operable, both built in the 1940s.  Nickel Plate Road No. 765 was teamed with Pere Marquette No. 1225, when the powerful pair sped a National Railway Historical Society passenger special through the Appalachians at Barboursville, West Virginia, on the Chesapeake & Ohio mainline on August 10, 1991.
