Grand Trunk Western, Illinois and Michigan

4:20PM, Durand, 20 February, 4:20 PM. Background, Left and Right, International Limited, Chicago to Montreal (154?); up front Durand - Detroit (164?).

While the Internatinal had mostly lightweight equipment, the Durand - Detroit train had four rebuilt heavyweights, and the first two cars still had the old classic green-with-gold color scheme. Is that a GP7 or GP9?

It’s actually one of two steam generator equipped GTW GP18s.

About what year was the picture taken?

1970
