Thanks everyone. Clearly, the B units, whichever diesel they were on, were not in the MNRR era, so this should be a PC or NH topic. Otto, if you would do the honors for me, we're clearly out of MNRR operations now.
Dutch finding a picture of the FL9 with a B unit is interesting. I'll pick up that book on Amazon, thanks for the tip, Dutch, and thanks to Tom, Noel, Otto, et al for their replies. This was just such a random memory to pop up, I really wanted to know.
As for GCT and B units, I recall the various railroads ran diesels into GCT in spite of a law prohibiting it due to a shortage of equipment, even while trying to minimize it. I'm sure B units were rare indeed. However, my question pertained to childhood observations in Mamaroneck, not in GCT. It could well have been that these units were running into Penn (still, NYC diesel ban) under intercity operations, or were borrowed from LIRR under PC umbrella?
Regarding the NYC units mentioned running on West Side Freight Line, how did these units avoid the diesel ban? Does that just pertain to pax terminals?
Next stop, Willoughby
