Ariel view of Dupont & Dufferin in 1950. From link.
Note the railway sidings used in the industrial area. No longer needed. Also why the railway just north of Dupont could become a GO Midtown Train corridor, as other industrial areas move out. Dufferin & Dupont would make for a good location for a GO Train station, especially for residents and visitors in the Galleria development. The bad news would be it will take decades to put the station in, if not the 22nd century, the way transit improvements go in Toronto.
