Caption: Think cool !!! This is an early February image of GO (GP40TC) #507 relieving the regular Tempo unit on this cold blustery day. I loved days like this. Everything white and not enough snow to get stuck in. The noonish #73 is going onto the CN Dundas Sub on it's way to Windsor from Toronto. GO 507 was sold to AMTK in 1988 and became their #199 and made return visits to Canada on the AMTK "Maple Leaf".
