During the steam days and for some time afterards, Oneonta was a busy yard for trains both out of Binghamton and Wilkes Barre. It was also an engine change point and crew change point and had a huge roundhouse. The roundhouse fell into disuse after the Alco RS-3’s took over. Eventually, traffic patterns changed and the yard at Oneonta was more or less replaced by a rebuilt facility at Binghamton and the crews were run through between Binghamton and Saratoga or maybe Mohawk Yard in Schenectady and Binghamton. The last major activity in Oneonta was probably the car shop which after the CP takeover was shut down and replaced by facilities elsewhere.
