Buffalo, Rochester & Pittsburgh 2-8-0 "Consolidation" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class I (Locobase 11867)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Vol 13, p. 201. Works numbers were 8419-8420 in March 1887; 8525, 8527 in April; 8842, 8848-8849, 8851 in October; and 11640 in February 1891; 12306, 12311, 12314, 12316 in October.

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.


Class I2 (Locobase 12032)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Vol 18, p. 201. Works numbers were 12785-12788 in June 1892.

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.
