Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 27, p.304. See George Woodman Hilton, American narrow gauge railroads (Stanford University Press, 1990), pp.488-490. Works numbers were 26002-26003 in July 1905.
This narrow-gauge line operated near Peach Bottom, Penna. It was originally projected to form part of the Peach Bottom Railway, which was to extend from Orbisonia on the East Broad Top all the way to the Delaware River. The Eastern Division actually ran only about 20 miles from Peach Bottom on the Susquehanna to Oxford.
This pair of Eight-wheelers operated the passenger service on the LO & S until its closing in 1919. The 6 was scrapped in 1919 and the 5 was sold in 1920.
