Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 31, p. 36 and Vol 43, pp. 195+. Works number was 31581 in August 1907, 33418 in May 1909, and 38808 in November 1912.
Most of the class operated for more than 20 years. The 1 and 2 were each scrapped in January 1930. The 7 followed in December 1933. But the 5 worked throughout World War Two before coming under the torch in Febreuary 1948.

After less than 20 years in Raritan service, the 6 was sold to the E N Wilson Company. Less than 3 years later, ENW sold it to locomotive rebuilder/reseller Birmingham Rail & Locomotive. In July 1926, Stewart Jones Company bought it from BR&L.
