The only industry that gets cars at Danville Jct proper,is Morin Brick. The use the ramp next to the road by the old grain mill(closed for 30 years or more,but once a rail user) to unload boxcars of brick. They also make brick just down the road in a large plant. SLRs (you were right,St.Lawrence & Atlantic-but St. L. Quebec in Canada) serves the huge Safe Handling facility(and expanding even more!!)at the current end of its Lewiston Auburn Branch that leaves the SLR main at Lewist Jct. where their engine-car shop is. Other inductries on the L-A branch are the huge intermodal yard(many containers to/from L.L.Bean in Freeport are handled here,LPG gas tank farms(2),lumber/plywood dealer,feed mill,plastics factory,and a transload warehouse(mostly paper)- 1 of 3 SLR serves,other 2 are in Mech.Falls & S.Paris. Safe Handling does NOT have a switcher based there,but SLR "train"#516,works from around midnight to 8:00 am switching Safe Hdlg & other inductries on the branch There is NO more dedicated SLR "pig train",they cancelled trains 546/547 3 or 4 years ago. "pigs" today go to and from on their regular freight to/from Island Pond,Vt. This is train393/394 which leaves around 6PM & the other arrives before sunrise or shortly there after. Guilford only serves one industry(besides Morin Brick ramp which is on their tracks) and this is the International Paper plant that makes cardboard boxes just by turnpike exit 12. Usually 5 boxcars a day into the plants enclosed siding. SLRs traffic towards Portland has sadly all but dried up. The cement facility there just closed and in peak years,an ooil transload facility(run by Safe Hdlg.) for the paper mills in Berlin & Groveton meant a daily train(that was "based" in Port;ands E.Deering yard. Now,only covered hoppers of raw means for B&M Baked Beans in Portland,and an occassional boxcar of lumber products for Hancock Lumber in Yarmouth(1/2 way to Portland from Danville) means only 1 or 2 trips per week. A mile up the Guilford mainline,towards Auburn is Hackett Rd. where there is a farm supply firm,a rare user of rail,but this is also the location on Rumford Jct.(tracks to Rumford taken up in 1952),but a long passing siding is the locale of frequent Guilford meets,especially trains PORI and RIPO,in tha late morning. These are the 2 that do the interchange work with the SLR at Danville. Bud
