Well, I looked in some books and ETT's. As noted, the line was single tracked from a new point, Tide, an interlocking controlled from Atlantic, to Atlantic itself. This was 50 mpph, rule 261 (CTC) controlled by Atlantic. The remainder was double tracked through 1967 or 68, as my 1964 ETT shpwa track 1 and 2 in service all the way to Tide, just east of Absecon, with 70mph speed for passenger and 50 mph for freight. After this was single tracked, no doubt because there was not traffic density to warrant it, it was converted to single track, manual block from Winslow to Atlantic, with block stations (not the same as the K-card type!) at Ham (Hammonton), Egg (Egg Harbor City) and Gate. I'm surprised Gate stayed in as the race trains were all but done at this point. It wasn't til 71 that the line from Winslow to Kirk was completely single tracked, altho this partwas entirely ctc'd from Winslow. Somebody have exact dates for winslow to Tide single tracking?
