Re: 3 GP38-2s vs 2 SD40-2s

Without careful research, I checked the internet which said a GP38 produces 61,000 lbs. of starting tractive effort and 50,000 lbs. continuous. The SD 40 produces 92,000 lbs. starting tractive effort and 82,1000 continuous.

So the 3 GP38's produce 182,000 lbs. and the 2 SD40's 184,000 lbs starting. I'll defer to more experienced railroaders but would suggest that under dry rail conditions there isn't much difference but on slippery rail, spreading the load over less powerful motors might be beneficial.
