He doesn't mention his sources, but I imagine that he's got pretty good connections inside Amtrak.The states of Minnesota and Wisconsin have requested Amtrak compile a study of adding a second train from Chicago to Minneapolis and possibly St Cloud. I will keep you posted as it moves along. I am hoping Amtrak will also choose a stop at one of the Northstar stations for this train and the Empire Builder, preferably Anoka, MN.
