A few years ago, I obtained an almost complete set of NYC employee timetables dated June 7, 1942. I am intrigued by Fultonham, Ohio on the Ohio Central Division, Z & W Branch. At Fultonham there was an interlocking at a railroad grade crossing with Pittsburgh Plate Glass. The interlocking had approach signals and the office was open 16 hours 6 days a week. What was the Pittsburgh Plate Glass operation?
