While I was watching a cn load a new crew ( this is Texas by the way) ,I noticed that I didn't recognise the engine type ##. One was a ef 620a ,??? news to me what it was. Did not get the unit #.
It's interesting how railroads have their own designations for units instead of using the actual model name and number.
The following information on CN's classification system is from Patrick C. Dorin's "The Canadian National Railways' Story": 1st letter designates locomotive builder G = General Motors or EMD M = Montreal Locomotive Works E = General Electric Company C = Canadian Locomotive Company 2nd letter designates locomotive usage: F = Road Freight P = Road Passenger R = Road Switcher S = Yard Switcher 3rd letter (if present) designates special feature: A = control cab (as in A-unit) B = no control cab (as in B-unit) E = equipped with generator for electric train heating G = equipped with steam generator 2 numerals after the dash indicate horsepower rounded down to nearest hundred 3 numerals after the dash indicate number of traction motors followed by horsepower Lower case letter at end indicates subclass based on purchase order. eg. MF-30a: MLW road freight unit with 3000 HP acquired in the first such order. (MLW C630) GF-430b: General Motors freight unit with 4 traction motors, 3000 HP acquired in 2nd order. (GP40-2) Hope this helps.
EF-620A sounds like a six axle general electric locomotive that generates 2000 hp? Big loco with no kick....thats even worse than a U28C.....or did I just do that wrong?
I think CNcndr_tyler is right. I don't think there are any locos of the EF-620a class on CN. . . if they even exist!
Such an engine does exist: the GE U20C, an export model never sold to Canada. It wouldn't be any more feeble than an SD38.
CN Patch Units I recently glanced at an article with a C44 - 9 in Conrail blue patched in CN. I didn't catch the numbers ....any idea (for modelling purposes) which numbers would be correct ?
