Norfolk & Portsmouth Belt Line 2-8-0 "Consolidation" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class C-1 (Locobase 14954)

Data from DeGolyer, Vol 65, pp. 214+. Works numbers were 54209-54210 in December 1920.

Locobase 431 describes the Pershing class of superheated Consolidations produced in the thousands by Baldwin as a standard class during and immediately after World War One.

Very few of these engines were delivered directly to US private railways, but once the great bulk of them had been delivered, this terminal switching line in Virginia ordered two. They were duplicates down to the 10" (254 mm) piston valves, although they trailed slightly larger tenders.

Chartered in March 1896 as the Southeastern & Atlantic, the N&PBL was formed in 1898 by a consortium of eight line-haul railroads to transfer freight throughout the port district over 12.1 miles of main track and 18.8 miles of yard track and sidings.

Both locomotives served the belt line until the end of its steam era and were scrapped in 1956.
