The Wallkill Valley wayfreight RV-9 (later RV-2/RV-9) made a round trip 6 days per week to Campbell Hall, with some local traffic (like cattle feed) and a lot of empties to interchange to the New Haven. Sometime he handled more than 50-60 cars to Campbell Hall.
The Catskill Mountain Branch wayfreight (technically a pick-up-and-drop train in NYC terminology) ran to Oneonta Monday, Wednesday and Friday, and returned the next day. Sometimes he had 30-40 cars, mostly cattle feed, for stations west of Arkville. Very little interchange at Oneonta with the D&H - usually a few loads of anthracite for local stations, and an occasional car of house freight or Cadillacs for Oneonta.
The Catskill Mountain Branch Yard Engine worked the former U&D yard, and spent all day, six days per week, serving local industries with all sorts of stuff in 1955. The track to the Colonial Sand and Gravel Co. cement mill hadn't been built yet (1958) but when it started up it took 20-35 cars of bituminous coal per day from the CMB Yard job. The West Shore crews also had a Kingston yard engine that served local industries as well as (I think) two tricks switching in the yard.
There were north end and south end drop trains running on the West Shore main out of Kingston, and the Alsen Switcher out of Kingston was good for 40-60 cars of cement and coal on a good day.
It made a good piece of business for the New York Central, and justified stopping a few trains at Kingston to set out and pick up.
