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 1,707 units and the second most prolific 2-8-0 class in North America, with the USATC S160 class rostering 88 units more. The three subclasses differed as follows: [4]

The various variants of the H6 formed the most numerous class of steam locomotives in the PRR. After the USATC S160, which had been developed for wartime use in Europe, they were also the most-built Consolidations. They were intended for freight trains on main and branch lines, local freight trains and as switchers.

In 1901 the PRR tested new 4-4-2 Atlantic's with a wider-belpaire firebox that was able to widen its burning space over its drive wheels and became an instant success that the Pennsy developed the H6a with this wider and better performing firebox to replace the poor-firing H6 class.

1 was a H-6sb 2-8-0 built by Baldwin Locomotive Works for the Pennsylvania Railroad in March, 1906. 1 was originally 3058, a H-6b which later was rebuilt by Altoona Works in 1913. Its class hauled mainline freight haulers, local freights and as switchers in yards.

In 1859, the Pennsylvania bought a controlling interest in the profitable western Maryland line and from that time, the CVRR's motive power design took its cues from the much bigger road. These 2-8-0s were duplicates of the H6 engines (Locobase 4795) going into widespread service on the PRR at the same time.

The 1499 and her sisters of the H6 class comprised one of the world's most numerous locomotive classes, while other engines are counted in the hundreds, the Pennsylvania Railroad H6 class is counted in the

2024年10月13日 · 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 triple heading long freight trains up the steep grades on the Pennsy.

L6 - PRR freight AC electric locomotives. M1 - mixed-traffic Mountain type, latterly mostly used on fast freight. N1s - Lines West heavy freight locomotive. N2s - USRA Standard 2-10-2, also used on Lines West. The 4-4-4 arrangement was rare anywhere, and on the PRR it was found only on eight experimental electric locomotives.

PRR H6sb-class 2-8-0 Consolidation No. 2846, built by Baldwin in 1905. There were ultimately over 2,200 class H6 locomotives built or modified from others of the H-series. Number 2846 had an incredible service life of 51 years. These Consolidations were the literal workhorses of the Pennsylvania for much of its existence.
