Pennsylvania Railroad Class HH1

The Pennsylvania Railroad class HH1s/Y3s are four-cylinder compound articulated locomotives that consist of six examples of ex-Norfolk and Western Railway Y3 class 2-8-8-2 (Whyte notation) wheel arrangement. These 2-8-8-2 steam locomotives were similar to the Norfolk & Western Class Y3 2-8-8-2s but with some PRR Alterations such as the keystone number plate that was mounted centrally on the small smokebox door and had fitted a little shelter known as a "Doghouse" onto the tender of the locomotive.
== The History ==
The HH1's roots trace back to the Norfolk and Western Railway, where they had once been in charge of general merchandise freight traffic and subsequently helper service. The Pennsylvania Railroad bought six of the N&W class Y3s in 1943. They were used in general freight traffic and helper service on the Pennsylvania Railroad similar to their lives on the Norfolk & Western. They were generally found west of Altoona, Pennsylvania. But their lives on the Pennsylvania were eventually cut short, due to J1 2-10-4 Texas type locomotives, and by 1949, all six of them had been retired from active service and cut up for scrap.
