I think you are mixed up a little bit on the Milwaukee Line. The "Little Joe" engines were basically paid for by the feds and practically given to the Milwaukee after the state department cancelled the deal to supply the engines to Josef Stalin. I knew folks that worked for the Milwaukee and they told me that the line was abandoned because the overhead conductors were worn out and copper was too expensive to replace them. And the whole line was not converted to diesel/electric. Huge parts of it had the rails torn out and it sits abandoned today.
