OK, John, going back to your post on GE motors. The last time I visited General Electric Transportation Systems in Erie, Pa., I met a retired engineer who worked in the Mine and Mill Locomotive Department since the 1940s. He explained to me what each model code signifies on most GE mine, electric and internal combustion locomotives. Don't know what happened to the pad I used to write all this stuff down, but I can try to answer your questions to the best of my knowledge.
Most GE mine and mill locomotives used the model nomenclature that we have been discussing. Here are some examples of various models and what they mean:
LS-2E30-A:
Locomotive
Surface
2 Traction Motors
30 Tons
Form A : First model
An interesting one:
LME-2C2C50-B2
Locomotive
Mining
Electric
2C2C: 4 Traction motors/Two axles
50: 50-Tons
B2= Form B2
LSB-2T4-K:
Locomotive
Storage Battery
2 Traction motors/axles
Form K
The TYPE only tells us what the unit is, tonnage, and how many axles/motors. This is true for every type of mine and mill locomotive no matter if it is a battery or straight electric. If I remember correctly, I think the FORM had to do with the different versions of a particular locomotive model. For example: Form A= first type, while FORM A1= changes in design or specifications.; FORM A3 additional changes to A1.
Now, straight electric and internal combustion "road" locomotives are classified differently. Here are some examples of what you would find on a builders plate:
Classification/Model/Type: B-B 130/130 4GHM 833
What does this mean? Here is the answer:
B-B: AAR Wheel arrangement
130/130 half of 130 is 65 Tons
4GHM833: Four GHM-833 Traction Motors
Another one:
B-B-250/250-4GE729C
B-B: Wheel arrangement
250/250= half of 250=125-Tons
Four GE 729C Traction Motors
Hope this sheds some light.
BTW, I think we should move this to another topic page.
