Hello Tom
I wonder how many times he (Jim P) got hit in the head by rapid fire "chalk" missals or chalk-dust-packed blackboard erasers slamming warp-speed into his head in a cloud of white dust as he gazed at trains out the window -- heh ! Remember any of those incidents with the "Bro's at the Mount ? Or with the "nuns"' in other schools elsewhere ?
i use to walk to E. 97th Street and Park Avenue where the NYCRR Park Ave Tunnel ended, and watch all the NYCRR & NHRR old ancient MU's and Box Cab loco of each road come and go there. Was always constant action on those 4 tracks. And then I had the IRT 3rd Ave EL and the IRT Lex Subway right by me for joy riding for 10 or 15 cent fare - later 25 cents. THOSE were the days - and lots of old equipment and variety of rolling stock classes.
The above two of my photos -- the top one is a view N.E. along the west curb of Third Ave., showing the near E.148th St south cut off end of the EL as cut back in summer of 1958, and the lower photo shows a view north from the s.w. corner of Third Ave. at E.146th Street, early summer 1958, showing the demolition upward towards E. 148th Street
