There appears to be a "flutter" of media coverage of late regarding proposed Chicago Iowa City and (maybe) Des Moines service. Simply go to Google, query something to the effect of "chicago iowa city train" and you will get some hits from various Iowa media sources.
Although a Chicago Des Moines "mixto" was part of the 1999 Amtrak Network Growth Strategy, I doubt if there was much more to the proposal than an excuse to feed some wired in consultants at the Feddybuck trough.
But this proposal meets the parameters of what 21st century passenger railroading is all about namely service to population centers, and a local level initiative including local level funding. I think there is a 50-50 chance this one just might work - and I just might use it myself.
Here is reference to the
Feasability Study as well as one of the several recent
news media reports.
