The West Lake Corridor is a proposal for commuter rail service to serve the city of Chicago, Illinois, and the cities of Hammond, Highland, Griffith, Valparaiso, Hobart, Cedar Lake, Munster, Merrillville, Dyer, and Lowell in Indiana.
It was decided in mid-2000 that population and commercial growth in Lake and Porter counties in Northwest Indiana justified an expansion of the commuter rail services offered by the Northern Indiana Commuter Transportation District (NICTD). A more recent study confirms the economic benefits; however, a later Associated Press-WJOB story indicates that NICTD has some doubt whether the community is growing at a rate that would qualify for federal funding for the project, and whether it could use the CN line to Valparaiso. A later study indicated that while the Lowell branch would attract 11,327 riders per day, a Valparaiso to Munster branch would not attract enough ridership, and that part of the plan would be dropped.
Lowell to Downtown Chicago – This service would extend a total of 45.8 miles from Lowell to Chicago along the CSX Transportation line, to the Monon Corridor, and then to Chicago as described above.
