(AP) – Passenger rail supporters in Wichita are planning what they describe as a “major announcement” this week.

The Wichita Eagle reports the announcement will be made during a news conference Friday afternoon at Wichita’s Union Station. City officials are characterizing the news conference as an “update on significant developments regarding passenger rail advocacy in this area.”

Wichita Vice Mayor Pete Meitzner will lead the news conference, along with business representatives who serve on his local steering committee.

Rail backers have been trying to persuade Amtrak to bring passenger train service to the city. One proposal would expand the route of the Heartland Flyer, which travels between Oklahoma City and Fort Worth.
