I need to call Scott this weekend about the SD40-2 project. I will ask about the E60s. I had three on order - E60CH in Phase II, and NJT, and an E60MA. I suspect there are other factors than just the numbers behind his decision.
I don't see P30CHs getting a lot of orders. SDP40Fs could be a possibility if the numbers are there for FP45s.
I'd love to see an ALC-42 but Siemens is not an easy entity to obtain a license from. In the meantime I have about ten F40PHs between K-Line and MTH.
