Data from

(http:/fp-www.wwnet.net/`dulong/dssa/locomot.thm). See also DeGolyer, Volume 14, p. 176. (Thanks to Chris Hohl for his 18 February 2015 email containing the information on the C-1.) Works numbers were 9389, 9395, 9398, 9402-9404, 9427-9428, 9432-9433, 9435-9438, 9441 in August 1888.

Passenger locomotives that carried on until 1928-1933. 100-101 originally numbered 115-116. The 111 was sold in 1905 to the Mineral Range Railroad, where it ran until scrapped in June 1928. Chris Hohl notes that the 113 was given smaller drivers in August 1905 and rolled on 63" wheels until it was retired.
