Hope this works.
The Blue Line at the Northwest corner of the photo is the FGLK Line ex CR/PC/NYC. The red Line is the Owasco River Railroad. The First small building it passes is Curley's Restaurant the line then crossed where Route 5 is then passes a lumber company (South West of the red line) then crosses Route 20 and then crossed over North Street then followed along the outlet on a trestle then crossed over Genesee Street and came on to Dry Land onto Osborne Street where it passed the D.M. Osborne Implement Factory where Wegmans is now the Line Split with the Track going up a 10% grade up Osborne Street next to the T Shaped building where it entered a Stub Yard on what is now Mill Street. There were 3 Big Mills there on on the other opposite bank of the outlet one next to the yard and one at the Switchback stub off of the Yard.
The section of track that curves to the South the switches back into where Wegmans is this was where the D.M. Osborne Plant there was the tracks were between a huge U Shaped building. There were between 30 to 40 sidings servicing other customers between the Osborne plant and the NYC Connection the ORR went as far as putting switches on the trestles to service industries from the back side on the opposite bank of the outlet its self.
Common communities that this little 2 mile line hauled were: Grain, Flour, Farm Equipment, Equipment Greece, Coal, Lumber, and other Mill ground Products. They used a 3 truck Shay for the most part of there operations oddly enough the 1st shay that they used was sold to the Marcellus & Otisco Lake Railroad. The 2ed Shay was leased from the NYC.
The ORRR was chartered by the Lehigh Valley Railroad who owned the right of way the line was then split 50/50 between the NYC with the ORRR Offices remaining in the Lehigh Valley Station on the 2ed floor and the NYC providing the Locomotive Power for the Line. I guess you could call this a shared assist Line??
