Matt, I got an email today from MTH with a link that won't be active until next week. It had a picture of the catalog's cover. I'll try to add it here for you.
My EMD SD70ACe is a CSX version. I settled on that after some wrestling with choices. I flipped a coin between CSX and NS. I originally wanted the EMD demo scheme.
I also built a GE EVO demonstrator. Mike Wolf said he wanted to build both models in G scale and sat on them for all this time. The G scale market is very funny on what sells. Either top end, or very cheap it seems? Years ago I talked to a guy who wanted equipment and he wouldn't spend $40-45 on a car of mine. He said he wouldn't spend over $20! Those types also want engines for less than $50. I told him "good luck on that".
