Caption: CN 7025 is a standard SW1200 switcher with AAR-A yard trucks, built by GMDD in September 1956.
The walkway below 7025's radiator intake is clean enough to sit on, at least in overalls.

CN predecessor Grand Trunk Railway built Danforth Yard - it no longer exists.
Vehicles of the era are at right; note the high television antennae above the homes in the background.
GO Transit Danforth Station near Main St has been mapped (approximate location).
