|Minneapolis & Saint Louis Gas Electric GE-29 near Minneapolis, Minnesota on October 20, 1957, Kodachrome by Dick Rumbolz, Chuck Zeiler collection. The location is somewhat speculative because the slide is marked MINN. Number GE-29 was built in 1931, body by Saint Louis Car Company (c/n 1550), the power plant was 400 horsepower EMC Winton Model 148 gasoline engine (c/n 491) coupled to GE electrical gear. I don't know who is responsible for the boxy structure on the roof but it's likely the cooling system for the prime mover. This unit went by the name 'Montgomery' (painted above the rear truck) and was repowered in August 1950 with a Caterpillar 400 horsepower Model D diesel.
