One way of looking at it that the purpose of this segment is to raise interest in passenger rail in Iowa, at least along the route Quad Cities-Iowa City-Des Moines-Omaha. We hope that Iowa's citizens and legislators will look across the Mississippi and say, "Hey, on second thought, we do want something like that after all."
Truth told, there's not much national interest in Quad Cities trains going up to 79 mph and taking 3 1/2 hrs to and from Chicago. But a real corridor train linking Lincoln-Omaha-Des Moines-Iowa City-Quad Cities-CHI will amount to something, come that glorious day. So we take one step.
Anyway, by allowing transfers at Chicago, the new train should feed passengers to trains like the Cardinal and the Capitol Ltd, and vice versa. And adding more train miles spreads the overhead over more trains, meaning a little less cost loaded onto the existing trains. So it will benefit the whole Amtrak system.

Last I recall, Iowa Interstate had not finished the engineering, probably understandably thinking the deal was off for good. So work could get done in next year's working season. Or not. LOL.
