Baldwin 2-8-0 H10s class steam locomotive
The Consolidation Type was a highly successful steam locomotive design of the latter half of the 19th century that would eventually replace the 4-4-0 American Type. The new Consolidation, a 2-8-0 design, allowed for more tractive effort with two additional driving axles and a larger boiler. The 2-8-0 steam loco type served around the world in thousands units with hundreds railroads companies.
Pennsylvania Railroad "Consolidation" class were named H Class and its first series built was the H1, with a total of 545 engines produced between 1875 and 1886. Later, a large number of units were built (in total, over 1.500, mostly between 1907 and 1916), belonged at many sub-classes, of which the H6, H8, H9 and H10 were the most important variants. Each version types differed in the cylinder diameter and pulling power.
The H10s class was built primarily for PRR Lines West (from Pittsburgh to Chicago), and featured a typical "Lines West" tender mod. 80F81a (or 80P81a) with sloping side coal boards at the top, to enable a bigger load of coal to be carried. H10 class was similar to H-9s, but with a 1" larger piston diameter (2" larger than the H-8s). All had Belpaire fireboxes and 273 units were built between 1913 and 1916 (95 engines by ALCO-Pittsburgh, 75 by Baldwin, 73 by ALCO-Brooks and 40 by Lima). Many H-8 and H-9 converted as well and used on lines east of Pittsburgh, Altoona and Philadelphia areas, as yard switcher or road-switcher on the branch-lines hauling local and regional "light" freight trains.
Thousand of "H" class PRR's steam locomotives were used until complete dieselization by the PRR that occurred after 1957.
