What was the schedule in the 60s of Harlem Division freight JNDO and its other direction (which I presume was symboled DOJN? The book Gone but Not Forgotten shows photos of it making up to depart Put Junction yard at 4 PM on a Sunday; however I assume this was not the weekday schedule since that timing would have it threading through New trackage in the rush hour!!
IIRC, both sides of the job were late evening start times. Crews worked JNDO (Put. Jct. / W. 72nd St.) one-way and returned on the next evening's DOJN.
However, depending on traffic, it was not unusual for the Sunday JNDO to be made up and ready to go in the late afternoon. Crew would report early and make the trip early in order to DH back home from GCT.
