This class's design was identical to that of the Consolidations that went to Huntington & Broad Top Mountain in 1886 (see Locobase 11868). The February 1891 engine was later sold to the James Bay Railway in Quebec.
All of the others were retired in 1912-1913.
Locobase 11867 describes the simple-expansion predecessors that made up most of this class. About 8 months after the last of the I class Consolidations was produced, Baldwin supplied this quartet of Vauclain compounds.
They were later converted to 20" x 24" simple-expansion locomotives before being scrapped in 1916-1917.
