Data from Interstate diagram published on [] (visited 26 Dec 2004)., supplemented by DeGolyer, Vol 41, pp. 166+. Works number was 36275 in March 1911.
This was very similar to the Interstate Consolidations shown in Locobase 6440 and joined them in 1920. It differed from them in that the Interstates had Southern valve gear.
The RF operated out of Blackwood, Va, connecting Blackwood and the Roaring Fork Mine.
