The Pennsylvania Railroad's class H6, H6a, and H6b steam locomotives were of the 2-8-0 "Consolidation" freight type, the most numerous class on the railroad with 2,032 units. The three subclasses differed as follows:[4]

Class Firebox Grate Area Tractive Force Driver Size #Built Years Built
H6 narrow 33.3 sq ft (3.09 m2) 42,717 lbf (190.01 kN) 56 in (1,400 mm) 189 1899−01
H6a wide 49.0 sq ft (4.55 m2) 42,168 lbf (187.57 kN) 56 in (1,400 mm) 1242 1901−05
H6b wide 49.0 sq ft (4.55 m2) 42,168 lbf (187.57 kN) 56 in (1,400 mm) 603 1905−13

In the 1920s, 699 H6a and H6b had superheaters added, and cylinder size increased from 22 in (560 mm) to 23 in (580 mm). These rebuilt units were reclassified to H6sa and H6sb.

Class H6 were used throughout the system as mainline freight haulers, on local freights, and as switchers in yards. They were frequently seen double- and tripleheading long freight trains up the steep grades on the Pennsy.[5]

During the period when the PRR was building the H-6 class, the railroad had effective stock control of the Baltimore and Ohio Railroad, and installed a PRR vice-president Leonor F. Loree, as president of the B&O. Subsequently, the B&O bought a large group of identical locomotives from the American Locomotive Company; these were initially classified class I-4, later becoming class E-24. The E-24 class had many variations, some being converted to switchers, or receiving superheaters and new valve chests. The E-24a was equivalent to the PRR H-6sb. None of the B&O E-24 class survived to the diesel era.

China

Around 1938, thirty H6sb were sold second-hand to the South Manchuria Railway (Mantetsu), which designated them Sorisa (ソリサ) class (Sori, from "Consolidation", and sa, from san, "three", to indicate the third class of Consolidation-type locomotives operated by Mantetsu). To distinguish these from the British-made Sorisa 1−7, the H6sb were nicknamed ペンソリ Pensori (Pennsylvania Consolidation). Of these, fifteen were taken up by Mantetsu, which numbered them ソリサ8 through ソリサ22, whilst the other fifteen were assigned to the Manchukuo National Railway, where they were numbered ソリサ547 through ソリサ561.

After the end of the Pacific War, both Mantetsu and the Manchukuo National were absorbed by the China Railway, which designated them class KD10.

Survivors

PRR #2846, an H6sb built in 1905 by the Baldwin Locomotive Works, has been preserved by the Railroad Museum of Pennsylvania with two other examples of the H class. #2846 was added to the National Register of Historic Places in 1979 as Consolidation Freight Locomotive No. 2846.
