I don't recall who the operator was to be, and it's a long story but the construction was to be funded by the feds and it was estimated to cost Wisconsin 7 mil anually though there were other municipalities and groups who saw it as a major boon and made offers to offset the bill.  It was a line to connect Chicago, Milwaukee and eventually the Twin Cities via high-speed rail.     It was already in motion under the previous administration including two partially completed train sets, a maintenance facility and other infrastructure.  Walker then got elected passed on the Fed funds, and told Talgo to keep building the trains before later canceling.  Talgo closed down for a while (eventually repoened smaller as a refurb shop) and other states got the 800 million. 

IMHO, it's a perfect example of what happens when a politician lets their distaste for a previous administration and their "government-is-bad" philosophy get in the way of common sense and ironically ends up wasting many (50+) millions of dollars, killing jobs and stifiling the very kind of economic gains that would typically have been part of their political platform.

When the suit was finally settled, Talgo recieved about 10 mil in damages and got to keep the two trains that Wisconsin had ordered and the 40 mil they paid for them. 

Here's an article about the settlement.
