Similar to C&O's H-8 class Alleghenies, but not as well known. Arrangement name on the VGN was "Blue Ridge". They had smaller sand domes than the H-8s and raised tender decks.
Bob Quehl (EMail:rquehl@adelphia.net) from Pittsburgh, PA writing in the Worldrailfans group in 2000 (http://www.worldrailfans.org/Forum/1998/Jan/2281650.shtmlon Feb 4 2000, 4:06), tells us this about the Virginian's view of the AGs they were about to get in 1945:
"Apparently it became known by some senior managers at the C&O that the engines were considerably overweight. They did not start to raise questions as there was a cover-up attempt by C&O and Lima, until the neighboring Virginian Rail Road ordered their own Alleghenies. The president of the Virginian, one Frank Beale, was a former high level person in the C&O and knew what the H-8 was supposed to weigh. When he got the specifications from Lima for the Virginian's engines, he could not understand why they weighed considerably more and one thing led to another. The Virginian had a lot of trouble getting their 8 Alleghenies delivered as the surrounding rail roads did not want that much weight on their rails."
Note that total engine weight on the 1942 Alleghenies was more than 18,000 pounds higher than on the AGs. The C & O's 1948 Alleghenies (Locobase 11065) were copies of these VGN 2-6-6-6s.
Scrapped in 1960.
