LAFAYETTE, Ind. (AP) — Amtrak has stopped taking reservations beyond July 1 for an Indianapolis-to-Chicago passenger line that could soon lose funding from the state of Indiana.

Indiana has contributed $3 million annually for Amtrak’s Hoosier State line, a 196-mile route that runs between the cities four days a week.

But Republican Gov. Eric Holcomb didn’t include that funding in his proposed 2-year state budget that starts July 1.

The Journal & Courier reports that aside from halting the line’s reservations beyond July 1, Amtrak is also contacting more the 500 people who’ve booked seats, warning them they might need to make other travel arrangements if Indiana lawmakers end the funding.

Amtrak spokesman Marc Magliari says the steps are a 90-day notice that the line might not be in service after July 1.
