As you can tell from my screen name I'm an N&W fan. But I do have a smattering of PRR models. My favorite is the 3rd Rail brass 6200 Turbine. I am continually amused by octogenarians who confuse my 30" long scale brass engine with a Lionel 671.
I've long said that you could put the PRR keystone logo on a soup can, and it would sell.
