Re: If I had to choose...

Chile...

The E6s used the same boiler as the H8-9-10 class consolidations, as well as the later G5 ten-wheelers. The K4s used a larger version (the K4s generated about 3600 hp while the E6s only could generate 2400 hp, which incidentally translates to 1200 hp per axle...STILL a world record!) of the boiler. In fact the K4s got it's big boiler from the Alco-built experimental K29s class locomotive.

And no, that's not a poppet arrangement you see, all E6s class locomotives used the PRR standard lightweight Walscharts gear (except for the rotary motion applied to the 1067 when she was built. That didn't last long though... see OP-14260 at the DPL site) The circular arrangement on the valve chest is the PRR standard snifter valve, which acted to break the vacuum generated while the locomotive is drifting.
