Public comment is being sought through Oct. 24 by the Northern Indiana Commuter Transportation District on a plan to double track the South Shore Line
NICTD expects to finish an environmental assessment in time for 2017 public hearings. After the completion of final design and engineering work, construction could begin in 2019.
The double-track segments would open in 2020. The $210 million project will add 25 miles of second track between Gary and Michigan City.
The South Shore Line currently has a 6.5-mile section of double-track plus multiple passing sidings.
Once opened, the new double track would cut the travel time to Chicago from Michigan City by 40 minutes to one hour even.
Although most of the new track will be laid next to existing rails, the project will re-route track now running down the middle of West 10th and 11th streets on Michigan City.
