Topeka ? The Kansas House gave tentative approval Wednesday to a measure laying the foundation for expanded passenger rail service through the state.

The bill would establish a passenger rail program and fund within the Kansas Department of Transportation. It also authorizes the transportation secretary to enter agreements with Amtrak or other carriers to expand service through Kansas.

House members were expected to take final action on the bill Thursday.

Kansas is among several states working to expand Amtrak service in the Midwest. Supporters say the bill would help expand service from Kansas City to Dallas.

The legislation would enable KDOT to continue developing the passenger rail line and seek federal funds to establish the route.

KDOT officials scheduled a news conference for Thursday to release the findings of a feasibility study on expanding passenger rail routes. The study is expected to offer four alternatives and begin the process for identifying a preferred route and required infrastructure requirements.
