There isn't a dead line to speak of at the TMC any longer. All the RDCs that were once there have gone elsewhere and the lone LRC locomotive, owned by the Toronto Railway Historical Association, will likely be stored indoors. All VIA F40s that have not been retired due to wrecks are still in active service.
A popular location for viewing and photographing the VIA and GO yards is from the Islington Avenue overpass which goes over the centre of both. On street parking may be available east off Islington on Judson Street which runs along the north side of Willowbrook Yard. Whenever I want to see something at the TMC I find riding a Lakeshore West GO train through the middle of the yards a convenient way to do that. With a Day Pass, for the same price as a return ticket, you can go back and forth between Mimico and Long Branch stations as many times as you wish.
