There's a ton of disinformation here. SO, here's the railroad companies, and the unions.
Here's a MUCH MORE accurate explanation of what's going on, from the Unions' side.
Note, that a LOT of railroad companies also buy a great deal of ad spots and donate to NPR. Don't listen (OR be highly critical what they say) to the news like CNN, NPR, etc. And for point; go cross-compare the list of rail companies to ANY article you read. You'll see no company names. But unions get dragged through the mud.
