An open house is scheduled in Duluth on the proposed passenger rail that would run between the Twin Ports and the Twin Cities four times a day.

The Northern Lights Express project's estimated costs, benefits, ridership and service plans are expected to be discussed at the open house beginning at 6 p.m. today at the Depot, 506 Michigan St.

Project advocates announced in December that the project could be up and running by 2020 if funding became available. The proposed plan is a scaled-down version of the original plan and would cost less than previously estimated, travel at a slower speed and have fewer stops.
