I was watching a video on the history of EMD and the FT103. At the end of the video was the credits. It listed the source of some pictures and slides from Hot Water ( Jack W.).

 It is interesting to see the full history of the EMD road engines and switchers. There was a brief history of some competition from Alco and a flash of Baldwin's releases.

There seems to be a line drawn where the steam era transfers to full diesel. I find it interesting to see how long the diesels were in service before the steam era ended. The video eludes to the fact that this model release from EMD seem to spell the end for the steam dominance that RR management held in high regard.

 I used to believe that once diesels arrived, steam quickly faded away. I always thought it was somewhere in the fifties. It's fun learning what really happened in history.

The first "diesel" freight engines were actually oil-electrics, built for the Dan Patch Electric Line in Minnesota c.1910. The railroad wanted to be an electric line, but started out buying boxcab electrics equipped with portable oil-burning electric generators inside them. Turns out they never did string wire, just ran trains with the boxcabs until the railroad was reorganized as the Minneapolis, Northfield and Southern in 1918 and steam engines replaced the boxcabs. The MNS became all-diesel (again) in 1950.

Every circumstance imaginable began to pile up against steam rapidly from around the mid thirties onward.  EMD used to say that Diesel did twice the work of steam at half the cost....maybe true when it was first said. By the fifties, it was ten times the work at one tenth the cost !  My favorite EMD quote...from when the SD7 was first developed.  "All the advantages of a Shay, with none of the disadvantages"   

Great stuff. I enjoy history finally! ( & that took a lot of years)

I can see most of the benefits. I was surprised at how long ago they appeared. Some of the EMD switchers shocked me the most. I never thought they were so old.

"The EMD SW1 is a 600-horsepower (450 kW) diesel-electric switcher locomotive built by General Motors' Electro-Motive Corporation (later Division) between December 1938 and November 1953.  "

1938!!! WOW.
