Caption: Canadian Pacific RS2 8406 and RS18 8745 lead a freight northbound over the West Toronto diamonds, passing the old West Toronto Junction interlocking tower as they cross over from the Galt Sub (via the Galt-MacTier connecting track) to the MacTier Sub. The bisecting tracks they are about to cross are for CP's North Toronto Sub, heading east through midtown Toronto to Leaside, and further points east on the Bellville Sub. This photo offers a better view of the old grade crossing tower in the distance at Osler Street, near where the MacTier Sub split off to the north.

CP had just four MLW-built RS2 units, 8405-8408, which were overshadowed by their well-known Alco RS2's (8400-8404, that lasted into the 1980's on CP's lines in the US) and the fleet of more populous MLW RS3 (8426-8461). Unlike the Alco-built units, 8405-8408 all had MU, so were often seen operating in mainline freight service mixed with other units. 8405 & 8408 were traded in to MLW for C424's in 1965, while 8406 suffered fire-damage and was retired in 1969. 8407 lasted through the 1970's in yard service out of St. Luc in Montreal, until retirement in 1982. By that time, CP's six remaining units were some of the final RS2's in operation.
