the question is did the santa fe use GP40’S or not ? . know they had GP40 X’S But did they also have GP40’s as i have 3 of them and dont want to use them if not correct.
1 that was inherited with the TPW merger and was wrecked and scrapped shortly after. It was numbered after the GP38’s as I recall without looking it up. They did not buy GP40’s new.
The Santa Fe had quite a few GP 50s which are basically similar to the GP40, except for the type and size of the radiator grilles. If you can buy or make up the appropriate radiator grilles, and renumber the locomotives between 3805 and 3854, you’ll be fine.
If you think nobody else in England knows the difference between a GP40 and a GP50, just change the numbers.
Bachmann made high hood GP50s which were only used by Southern and later NS.
But if you like, you could combine the GP40 cab with the GP50 hood. However, the radiator grilles of the GP50 were basically deeper and of the “corrugated mesh” pattern, rather than the flat grid on the earlier GP40s, and that’s the main visible difference.
