Hey John... FWIW the PRR operated THREE narrow gauge lines in the 20th Century, so it's not exactly off-limits here. What's really interesting is that at least one narrow gauge F-odd class (2-6-0) locomotive still exists, and is painted and lettered PENNSYLVANIA.
Lets not to forget about the PRR interchange with the EBT at Mt. Union as well.
The really neat thing is that the Bachmann On30 passenger cars (based on OR&W prototypes...one of the PRR controled narrow gauge lines) are available painted and lettered for the PRR... which is exactly how they looked in service. So the PRR cars they offer are actually correct...
who'd a thunk it?

p.s.... ALL of PRR's E6s locomotives were hand fired, and NONE received power reverses while in service.
