Ahhhhh, thanks, I needed that.
The RF&P was a classy line that recognized the importance of preventative maintenance, which is how GP35s ended up on the point of a hot intermodal in the late 1980s. Show me other lines that did that often. And, you just have got to love the SW1200 on Flexicoils doing the same thing (see your first link).
Did you notice the baggage/steam generator car with the bent frame in the shot with the original AutoTrain (see your third link)? Good stuff. Scary, but good stuff. Those U36Bs had seen better days, and they weren't even that old yet!
In your fourth link, a prototype passenger train for small layouts.

Thanks,
Dave
