The Northern Indiana Commuter Transportation District was told this week that work remains on schedule on the double-tracking project on the South Shore Line in northwest Indiana.
The report said the project is expected to finish in about 16 months.
NICTD President Michael Noland said trains should resume operation between Michigan City and Dune Park this summer.
Laying of track is expected to be completed between Gary and Michigan City by November. South Shore personnel will then conduct testing of the line with the goal of starting revenue service in May 2024.
Nolan also said work on the 8-mile West Lake Corridor is 15 to 20 percent complete. That line will connect Dyer and intermediate stops with the South Shore mainline in Hammond.
During the meeting of the NICTD governing board, South Shore officials said ridership of the commuter service between Chicago and South Bend, Indiana, remains less than half of pre-COVID 19 pandemic levels.
However, South Shore management expects ridership to soon reach 55 percent of what it was in 2019, the last full year before the pandemic began.
