(St. Paul, MN)  --  The future is uncertain for a proposed Minneapolis-to-Chicago Amtrak route.  Minnesota lawmakers left money for the new train line out of the current state budget.  In Wisconsin, lawmakers gave their approval to 300-thousand dollars for environmental studies to be conducted.  Backers say the big project would cost between 130-and-140-million dollars.  The lack of Minnesota funding puts the idea on hold, for now.
