As an individual that is familiar with the route form Chicago to Minneapolis/St Paul, and having actually worked the Hiawatha's as a passenger trainman ( and to my knowledge, there is only one other person that frequents this forum that can claim that), I have to agree with Mr. Norman that the equipment that should be purchased for this service is equipment based of the California car or surfliner platform. The Tango is overkill and you will not gain much if anything, even on the river between La Crosse and Minneapolis.
Governor Doyle is out mavricking around, when what should be happening is a thorough discussion among those states that have Midwest corridor service ( WI,IL,MO,MI as well as Amtrak about a joint equipment purchase of cal car/surfliner based equipment for the entire corridor ( including expansion) The 2 14 car talgo sets the state of Wisconsin is purchasing is not a great capacity improvement over the current equipment sets in use, and do not allow for service expansion that will require a 3rd set of equipment for any more trips between Milwaukee and Chicago, and in any case, they will be the odd equipment in the corridor.
Again.. My view is that equipment based of the California car or surfliner platform is the way to go...
