Typical suburban tank locomotives that pulled SIRT trains until the line was electrified in 1906. All three were then sold to locomotive rebuilder/recyclers, the 16 and 18 bought by Southern Iron & Equipment and 17 by Birmingham Rail & Locomotive. As often happened with former transit tanks, two of the three wound up with logging companies. Ex-16 went to Lodwick Lumber Company of Lodwick, Texas.
Ex-17 had a more involved second life. It operated for Arkansas Milling Company in Turkey Creek , Louisiana for less than a year before being sold back to BL & R in 1913. After its conversion to 2-4-0 tender engine, thsi locomotive was sold to Scott Lumber.
Ex-18 was sold first to Loyalhanna Coal Company, back to SI & E, then to Kaul Lumber in Hollins, Ala, then to BL & R.
They were retired by 1928-1929.
Alvin F Staufer & Lawrence W Sagle, B & O Power (1964) says Cooke built 7-15 in 1885 and the railroad's own shops at Clifton followed with 16-22 later on. According to a compilation of Cooke locomotives by B.Rumary (25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND) and supplied to Locobase by Allen Stanley in March 2004, the only 2-4-4Ts for the Staten Island were 10-14 (Cooke works number 1748-1752 in February 1887.)
And from the 1954Raildata collection of B & O locomotive diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection, the notation is that the whole class was built by the SIRT in its own shops in 1905-1910. This last is probably explained as a rebuilding program with new boilers.
