I think that would do a lot to help out with petroleum usage and AGW. Diesel trains get like 400+ MPG. Big trucks driving across country… I’m sure it’s close to a single digit number.

Your 400+ is not actually in mpg, but in miles per gallon per ton of cargo carried. Fully loaded freight trains usually average <=2 mpg.

re: #66 Aceofwhat?

Newer trucks (400-500hp) get 7-8mpg. Older trucks…less.

8 mpg @ 40 tons = 320 miles per gallon per ton average for fully loaded 18 wheelers. Half that in heavy traffic.
