Train Frequency Alony Susquehanna River Above Pittston

I've driven from Coxton Yard up to Tunkhannock, along the Susquehanna River. It's a pretty ride, and it follows a R&N line. How many trains in a week use this line? When do they run? Do they go all the way to Towanda?

The R&N runs one turn six days a week from Coxton up to the P&G plant at Mehoopany. The call time (at least on Sundays as of last September) was 6 AM and the engineer on this run said he would usually be back in Coxton at around 2. It was a fairly easy chase southbound after getting some pictures from the road that runs behind the mill.
