Thanks to Alan for the submissions, and to Paul, for posting everything!
These examples are great for passing on the basics of Diesel-Electric Locomotives.
One minor point:
The text describes starting of the Prime mover (Diesel Engine) via the Main Generator (by applying Power to the Main Genny, as to make it rotate).
This was done on a few "First Generation" Diesels - such as EMD's "E" Series and a few Models from General Electric and Alco, however, many of the "latter 1st Generations" by EMD - such as the infamous "F" Series (FTs, F3s and the well known F7s), along with the "Newbee GP" Series (GP-7, GP-9) had Starter Motors.
For 2nd Generation Locomotives in the General Motors / Electro-Motive Division line (GM / EMD), most - if not all, of the Yard Switchers (AKA "Yard Goats") still used the Main Genny as a Starter Motor.
No "Road / Switcher" units used the Main Genny as a Starter - all contained specific duty Starter Motors.
I am unsure if General Electric's 2nd Generation Yard Goats used Starter Motors or the Main Genny.
As for Alcos', there were no new Models produced by the mid 1970's, as they began Bankruptcy procedures by then (sad).
Glad to see the Railfans alive at ECN! Feels like Home again!
For those still kind of curious to the Diesel-Electric Locomotive priniple, it's simply a "Motor-Generator" set, sitting on top of a Frame, which has Electric Motors on the Axles; and these Axle mounted Motors are driven by the Motor-Generator set riding on the Frame.
