Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 53, pp. 322+. See also a brief account of the TVRR at [] . Works number was 41881 in February 1915.
Baldwin produced two 3-foot gauge locomotives for the TVRR. Both were rated as "passenger & freight" engines. (See Locobase 14339 for the 4-4-0.)
Although both had the same driver diameters and virtually the same tube lengths, this Ten-wheeler burned its coal on a larger grate in a shallower firebox. Its extra set of drivers contributed to a third-greater adhesion weight.
The TVRR was a narrow-gauge shortline that built 27 miles (43.5 km) of track about 40 miles west of Harrisburg, Pa, between Port Royal to Blair's Mills. between 1892 and 1895. Customers could take either of two daily trains in each direction, one in the morning and one in the afternoon. Riders remembered taking the train to school and traveling to the Leonards Grove fair each year.
The line closed in 1934.
