General History:
As the 1930s drew up, the Pennsylvania Railroad began to see the deficiencies its pre-existing motive power had become apparent. Train often had to be doubleheaded, or even triple headed. The S1 duplex was not able to go much on the PRR. So, the PRR got a new mechanical engineer, an Italian immigrant named Agusto Bianchi. Bianchi analyzed the issue, then, he made his big conclusion announced at the PRR headquarters in Philadelphia. He declared that it was not only time to begin operating bigger and stronger engines, but it was time of make them fast. Hence the development of the P series Hudsons (called Keystones by the PRR), U series Berkshires, R series Northerns, and even a proposed Texas type of their own design, as opposed to based off the C&O T1. Plus numerous articulateds similar to those of subsidiary Norfolk and Western. 

Classes and their histories:
  • The P1 4-6-4: The first 4-6-4 steam engines. These were built in the 1930s when the PRR wanted a larger engine than their K4 Pacifics to haul heavier trains. The result was to simply extend the K4's trailing truck to allow for more weight distribution. However, they did not prove to be signifigantly more powerful than the K4s, and were even seen working along side their predecessors. These locomotives were known by the PRR men as "Keystones."
  • The P2 4-6-4: Before the C&O's T1 Texas type was tested, leading to the conception of the J1, the PRR did similar tests with other railroad's engines. One of these was when the PRR tested a Santa Fe 3460 series 4-6-4. The end result was to create the obligatory mods. Creating the "Super Keystones."
  • The J2 2-6-6-4: During WW2, the PRR made their J1 Texas types by testing a A class from subsidiary Norfolk and Western, and a C&O T1, then comparing them. Eventually, however, the PRR decided to create an engine based of the N&W A class after all. Using it to build the J2 2-6-6-4s. These were often used east of Pittsburgh. With some even being sold to the Southern railroad.

I would have put the P2's bell under its headlight. Still an impressive design.

I'm tempted to call the J2's an FG1, as per PRR standards for articulated power.

I actually renamed it that in a latter deviation.
