The South Shore Line is wrapping up work on the $950 million West Lake Corridor project. The $650 million Double Track NWI project to add capacity along the traditional east-west Shoreline route is done.

That checks off just about everything in the railroad’s current strategic plan, said Michael Noland, president and general manager of the Northern Indiana Commuter Transportation District, which runs the South Shore Line.
