Back around 1964 I remember often seeing what I believe was a mail train on the Hudson Div., headed west through Tarrytown right around midnight Saturday (probably ran other nights too, but I remember Saturdays). It was diesel powered, so it didn't originate in GCT. I guess it must have come up the west side. Can somebody tell me about this job --- exactly what it was, where it went, etc.
That was probably Number 13. In 1965 it was scheduled to depart 30th Street at 10.55 p.m., passed DV at 11.39 p.m., Harmon at 12.15 a.m. and Albany at 2.15 a.m., Eastern Standard Time (Daylight time was one hour faster, but the railroad did not observe it in 1965). No. 13 handled mail and express from the 29th Street Post Office Facility and the 33rd Street Railway Express House, daily except Sunday, from New York to Chicago. No. 3, another Mail and Express train, followed it by about two hours.
Their eastward counterparts, 4 and 14, terminated at Harmon. There were three other westward and four eastward mail and express trains scheduled each day just between Harmon and 30th Street. They handled most of the traffic from 4 and 14, as well as mail and express cars that moved beyond Harmon on the regular passenger trains. Switching mail and express cars into and out of passenger trains in conjunction with the engine change was a big deal at Harmon.
