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 …

Oct 22, 2004 · In 1901, Altoona constructed many class H6 and H6a (2-8-0) engines designed by the Baldwin Locomotive Company between 1902 and 1905. These were followed in 1910 by class H8 locomotives and, in 1913, by the H9s and H10s.

These 2-8-0s were duplicates of the H6 engines (Locobase 4795) going into widespread service on the PRR at the same time. When the Pennsy finally took over the CV in 1919, these locomotives were dropped into the H6 class and renumbered.

Oct 13, 2024 · 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.

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.

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.

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.

Adams's account of the development of the H6 class Consolidations says (p 52) that the F1 design was a definite improvement on the then-current H3s: "[t]ractive effort was up 16%...and the weight showed a 10% increase.

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.

Pennsylvania 2846 (H6) Description: 1905 by Baldwin Locomotive Works, Philadelphia, Pennsylvania.At the dawn of the 20th century, the Pennsylvania Railroad billed itself as the “Standard Railroad of the World,” emerging as a clear leader in American railroading.

Apr 18, 2018 · This one is a PRR H6 2-8-0 built in 1905 by Baldwin. The Pennsy had an amazing 2,029 H6 locomotives and for a time it was the most common freight hauler on the railroad. It was retired in 1956 and later added to the PRR historic collection.

locomotive PRR No. 1499, class H6a, more needs to be said. 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 thousands.* To properly understand the 1499 we must go back to the middle 1890 's.

Feb 2, 2003 · H6: A Lines East design produced in huge quantities. The original H6 (189 built) had a narrow firebox between the frames, but the H6a modification had a broad firebox straddling the rear drivers. 1242 of them were produced. The H6b had piston valves and Walschearts valve gear; 603 of this version were built.

Nov 28, 2015 · On 12-31-1952 there were still 8 H6sb locomotives remaining in service. The table shows 5 H6sb locomotives at the end of 1953 and then just 2 in 1954 – 56. The only scrapping dates shown in rosters are for #9979 (5-52) and 9988 (1-53); the others are unknown. Now that's what I call assistance!

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 …

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.

Pending checking those, I think there were also boiler diameter differences between the early Atlantics and the H6 subclasses. I drew the data above from the PRR Atlantics page and their PRR 2-8-0s page from http://www.steamlocomotive.com

Feb 3, 2022 · Here are some things to think about for those folks calling for a mass produced H6 and spouting this “2000 H6 class engines” stuff.
