IIRC NIMX (aka Naporano) scapped U33Bs and NJ(DO)T had some ex-CRI&P coaches in E-Port in the early 80s.
Over on Railfan.net, in the Jersey Central forum, its' possible to find a shot of the RI RDC that was used for parts. The pic was taken in the early 80's, it had been cannabalized for most of the 70's, but the cool RI lettering was still above the windows! I believe the # was 903, I could be wrong.
The only other RI RDC pic I ever saw was in TRAINS, in the farewell to the ROCK issue. An anonymous shot of a Budd flying across the plains. Awesome!
