This photo of another heavy pacific in Terminus, shows some the famous arches that were so well known as part of Underground Terminus.  The city of Terminus was built up a level from the original city, therefore allowing streets to cross over the rail line and eliminate grade crossings.  This made for some very interesting scenes, especially as photograph from the so-called Terminus railroad gulch.

Doubleheaded Mikados blast forth from Mount Frigid's North Tunnel with a southbound freight. Even on the relatively short trains seen on the Bluefield, doubleheading was often necessary. The Bluefield was primarily a coal hauler, and most of that coal was bound for the connection with the N&W. 

Heavy Mikado, 672 makes her way through the maze of switches at the north east end of William's Ridge. She has just finished switching out her freight cars and is headed to the engine terminal at Mount Frigid.

Bluefield Berkshire number 777 was the primary modern steam power used on the Southern Allegheny Division for fast freight service. Even after the N&W purchased the line, B&AC's 4 handsome Berks continued to hold down a lot of through freight assignments. The extremely steep grades in combination with short sidings, limited the length of most freights. Bluefield later leased 2 Berkshires from Nickel Plate to supplement their modern power and retire older Mikado and consolidation types.

1913 Bluefield and Allegheny Central Map.

This is the way the Bluefield and Allegheny Central Railroad appeared in 1913. The map was not to change much in the next 50 years except for the addition of some branch lines. By 1950, B&AC was controlled by the Norfolk and Western, but continued to essentially run as its own entity into the 1960s. Trains north of Fairmont operated with trackage rights over the New York Central to Pittsburgh.
