PRR superpower generation 3: T1 and cousins by mrbill6ishere PRR superpower generation 3: T1 and cousins by mrbill6ishere
Based on sprites by :iconandrewk4:.

As the 1930s loomed, the Pennsylvania railroad realized that things were going to have to change if they wanted its locomotive fleet to be strong enough to handle the traffic. Their solution was to hire Italian engineer Augusto Lombardi. Who was immediately commissioned to analyze the current steam engine fleet, and declare what the new power should be. Lombardi eventually became the Andre Chapelon of North America. Creating engines that were efficient, powerful, and fast. Though some never got past the prototypes due to war or other factors. They started out as simply pre-existing PRR engines with larger trailing trucks and larger fireboxes. But they soon developed into original designs with the latest steam technology.  With some even bearing larger fireboxes that required 6-wheel trailing trucks.

The second generation consisted of the three steam engines listed here. These engines continued the new concept of numbering PRR engines in blocks. Which was begun with the M1 Mountain class. 

The T1 4-4-4-4: This engines needs no introduction. Beyond the fact that many off these engines would later be redesigned to improve maitenance As well as the fact that there would be several still existing today. As said, after their modifications to improve maitenance and performance, the T1 would go on the prove them selves true power houses. Rivalling the R3 4-8-4s, and even most early diesels. All around, the Duplexes would be the same.

The R4 4-8-4: Theses 4-8-4s, called Mini-Duplexes, were built along side 6110 and 6111. They were to be used in case the T1 didn't prove themselves well. But due to the fact the T1 eventually go the proper modifications, only six were built.

The S3 4-8-6: Prior to the modifications given to the T1s, one solution to their problems was the creation of the 4-8-6 engine. These 50 strong engines, known as Uniplexes, not only had better adhesion than the T1s. But they could also haul heavier loads. But due to the eventual improvement of the T1 design after WW2, only 60 were built, and they mainly worked on fast fright or generic passenger trains. By the 1960s, only a few were still on the PRR. As most had been sold off to other railroads. Namely the Southern Railroad.

I can see it now. Roughly the DBHP of an Allegheny at over 120 MPH!!!
