The last 3 customers toward Pittsford IIRC were T.J. Zornow in Pittsford, and a couple liquor distributors near Pittsford Plaza - without double checking, I think it was Rochester Liquor and Eber Brothers. I also believe a short stub remained a bit longer just beyond the Can Of Worms to serve Domine Builders Supply.
The last rail traffic was about 10 or 12 former Amtrak passenger cars which were moved to Pittsford in 1982 or 1983. They were bought by a developer who intended to make various shops and offices out of them. Conrail set the cars just past Domine, and a rented Trackmobile took the cars to Pittsford in two trips. Motorists and residents were amazed to hear a tinny-sounding horn and see a roaring little machine dragging what appeared to be a passenger train merrily along the long-dormant track!
The developer had bought the cars before obtaining final zoning approval. There were enough snobbish noses out of joint that the project was defeated and most of the cars were soon scrapped. A couple were sold to the Depot Restaurant and survived another 20 years.
