@CookiesAndGuns95, the rear cylinders were reversed because if they were not, the firebox would have to fit between the drivers, resulting in a smaller firebox, less grate are, and thus less power. There is a link to a website for the engine facility that service almost all of pennsy experimentals, but it wont let me post it in the comments. Sorry. Try looking up "crestline prr engine facility"
@CookiesAndGuns95 all i know is that the rear-driving-cyclinders were a poor choice. Because the Cyclinders would wear out due to the hot,dusty firebox.

It's really a shame that once the PRR finally perfected their duplex locomotives they had to get rid of them for diesels.
