Locomotive horsepower

[GP40-2]

Torque really isn't a relavent measure here.

What????

If prime mover torque isn't relevent, please inform us what is spinning the main traction alternator to produce electrical current.

I suspect your response will be amusing.

FYI:
GEVO (4400 Traction HP) engine produces 23,550 lbs-ft torque @ 1050 RPM
EMD 710 (4300 Traction HP) engine produces 26,500 lbs-ft torque @ 900 RPM
GE HDL (6000 Traction HP) engine produces 32,100 lbs-ft torque @1050 RPM

Your typical V-6 found a late model car might produce 250 lbs-ft torque.

 Not sure about the tourque. The book I said above doesn't have it listed. As are as trains go...I think tractive effort (measured in pounds) and torque is the same. not 100% however.

 This piqued my curiosity as well. I like big horsepower numbers, but being a car guy too, I am more impressed with torque output as a realistic measure of power. Is there anyplace to find torque ratings?

Is there a web site that will tell you the horsepower rating of different locos?

 

Website...not that comes to mind...only think I could think of is try googleing "EMD SD90MAC specs." or something like that and it might work. Otherwise I would recomoned "Field Guide to Modern Diesel Locomotives" by Greg McDonnell. Its published by Kalmbach. Its a really nice book,  it tells the HP, model of engine traction motor, etc, and a little history on each type. It had MK, EMD, and GE diesels in it. Its worth every penny to me. Hope that works for ya.
