in October 1907.
As this railroad penetrated the timberlands on the Virginia-North Carolina border, it added to its narrow-gauge Mogul roster. A relatively long wheelbase suggests a preoccupation with light rail loadings.
J W Truitt was the broker for this locomotive, which was one of few bought by Camp from Baldwin. It was considerably larger than the narrow-gauge engine of 1894 described in Locobase 12131.
in February 1913.
Camp's logging operations called for lightly loaded locomotives and like many such companies, procuring a Prairie offered a useful combination of power spread out over 5 axles.
The 28 later went to Gray Lumber Company, which scrapped it in 1951.
Camp Manufacturing operated in southeastern Virginia near Suffolk and this little logging Mogul fit right in.
The specs for this plantation Mogul indicate what the little engine was up against. It was expected to scale 3 1/2 to 4% grades, go around 90-ft (27.4-metre) radii curves, and be kind to 35-lb/yard (17.5-kg/metre) rail. They too were supplied by Ernst Wiener Company, which increasingly looked to gasoline power for the sugar-central engines it ordered.
