Wednesday is the first anniversary of the line's three-year partnership among Amtrak, Iowa Pacific Holdings, the Indiana Department of Transportation and cities along the route.

In May, for the first time since Iowa Pacific took the train over last August, ridership showed a year-over-year increase. Revenue is up, too, but the train is still a long way from profitability.

Iowa Pacific has already has added free Wi-Fi, improved dining options and more than doubled the number of passengers it can accommodate. It also hopes to add more trains -- up to 14 per day.
