Class Details by Steve Llanso of Sweat House Media

Class 6 (Locobase 15496)

Data from DeGolyer, Vol 80, pp. 592. See also Locobase 12447 on the history of this Pennsylvania short line. Works number was 61306 in April 1930.

Although the KVRR bought this locomotive near the end of the third decade of the 20th Century, they managed to have it limned in Turn-of-the-Century colors and piping. A sort of "retro" look that went with the 60 lb/yard (30 kg/metre) rail, small size, and light weight of the locomotive. The specs reveal that the cab's back wall was only 40" (1,016 mm) from the backhead, which contributed to a compactness of line. Only the use of 8" (203 mm) piston valves betrays an intrusion of nearly modern design.

The KVRR's procurement of this mixed-traffic engine may have been sparked by a 1927 agreement between the railroad and the Pennsylvania Railroad for the KV to handle passenger traffic on the Milroy Branch, as the KV was now known. The actual termini were Reedsville and Lewiston. This service was sustained until the end of 1939. Within months, the line had been pulled up and scrapped.

Such a relatively new locomotive deserved a second career and it got one, beginning with the disposal of the 3 to locomotive rebuilder/reseller Birmingham Rail & Locomotive. BR&L found a buyer in the South Georgia Railroad of Quitman, Ga. The 6 ran on the SG until it was retired and scrapped in 1955.
