Thats quite a time frame,as "milk",from a creamery,or 2 ,in Colebrook,came down on the mixed train,and was set at Quebec Jct. for the passenger job from St. J to lift,but by mid 58',this was gone.
Starting at N. Stratford,the GT had what local business that was there,New England Stave & Heading,for wooden barrels,but they were winding down in the 50's,but probably lumber there.
Don't know if Lovejoy's Pit,shipped out any revenue aggregate,or just ballast and sand. Colebrook had the creameries,as well as a feed and grain store,which still got an occassional boxcar of bagged feed in NSRC days;was Agway at this time in 70's. Colebrook also got in coal(hoppers) and fuel oil and gasoline in 10,000 WRNX tanks(Gulf). There was also a smaller dealer in West Stewartstown. My cousins husband was District Mgr. for Gulf in Portland up through the mid 60's and they were the last to ship by rail to their "jobbers"(who switched to big trucks!!!). West Stewartstown also loaded pulp,as did Colebrook.
Of course,Ethan Allen was the sole reason for keeping the line open by the State,after MEC abandoned it. Also,a lot of pulp wood was loaded at Beecher falls,and I think this went down to N.Stratford for the GT to take to an IP(?) paper mill in N.Y State.via CN etc. If I recall,a lot of this pulpwood went out in older boxcars!
All I can recall at present. Hope it helps a little. Bud
