Yep, plenty of the freight world runs on 1940s and 50s era diesels. These were built in 85. They are some of the most efficient engines out there. Hell if you’re worried about efficient send this to Amtrak to replace their 1941 built sw1’s and you’re ahead. There’s freight companies running even older locos too.

This requirement was clearly made by someone who doesn’t know the freight rail industry at all. Freight trains are so efficient that the fuel costs are low no matter what. The biggest problem is upgrading the 1940s and 50s equipment out there to newer models since there’s little incentive. Here’s a perfect upgrade for those trains rendered useless by politicians.
