Good Day Gentlemen,
Thank you for posting and providing your insight. Perhaps someday one of the model train companies will present the prototypically correct SD75M’s, SD75I’s, SD70MAC’s, and SD70M’s. Time will tell I just wish it was soon.
To me the Santa Fe SD75M’s and BNSF SD70MAC’s are fantastic! Runners up, I like the SD70M’s with flared radiators too. I think the UP and NS has this model.
Best regards,
Frank Swafford
