WNYP - locations for meeting trains?

On the WNYP (ex-Meadville Line), are there siding locations that used to meet the coal trains regularly (other than at the yards - Meadville, Olean, etc.) I'm thinking of the overhead NS coal trains which run, and am wondering where they would meet if there were opposing trains on the route.

I think there was a set of radio-controlled switches at Columbus, PA - not sure of its length; I assume that's one location. Are the sidings at Cuba, Hinsdale, Salamanca ever used for meets?

Columbus, Salamanca, and Scio (Wellsville) have been used for meets The siding at Cuba is currently used for car storage.
