WHAT is claimed to be the world’s largest steam locomotive is set to make its heritage-era debut hauling passenger trains on July 1.
The Western Maryland Scenic Railroad has set the official roll-out date for restored Chesapeake & Ohio Railway H6 class 2-6-6-2 No. 1309.
The Fourth of July week will feature a variety of regular trains, special moves, celebratory events, and railroad activities.
Turned out in September 1949, No. 1309 was the last Class 1 main line engine built by Baldwin, ending a century of production in which the firm turned out more than 70,000 locomotives.
