Hey Nick, another PC Fan here chiming in. I only decided to go back into O scale about a year or so ago, and haven't had a chance yet to build a layout. I do have a Williams semi-scale GG-1 in PC and also a PC caboose. Back in my N Scale days I had PC engines and equipment, as you can see in the photo.
I spent many a lazy warm day by the NE Corridor watching the PC trains run by. Sadly, I seldom took my camera!!
I saw Robert Kennedy's Funeral Train when it went through Baltimore. My father took photos of it. I'll have to see if he still has them.
