Some eastbound South Shore commuter service lines have been restored with a limited number of trains operating from Chicago, an NICTD spokesman said Thursday night.
Trains 15, 119, 19, 121, 123 and 101 will operate from Chicago. The westbound Train 22 will be the only one operating between Michigan City and Millennium Station.
All other services for tonight have been cancelled, said John Parsons, spokesman for the Northern Indiana Commuter Transportation District.
Earlier in the day, trains kept losing contact with ice-covered overhead wires, forcing NICTD to suspend services until weather conditions improved. Eight out of the district's nine westbound morning rush-hour trains were affected. Crews worked to return passengers on stopped westbound trains to their originating stations.
Some trains lost power and others were underpowered, Parsons said. Trains that lose power also lose heat, he said.
Parsons said one train lost heat and was stuck west of the Torrence Avenue bridge and the Hegewisch station in Chicago. That train was returned to the Hegewisch station, and passengers were able to enter the station for a break, he said.
Metra was honoring South Shore tickets Thursday, and updates on delays were to be posted at mysouthshoreline.com, according to a NICTD alert.
Freezing rain Thursday also wreaked havoc for drivers, causing temporary closures of the Indiana Toll Road.
Indiana State Police shut down the Toll Road in both directions in Lake County early Thursday after icy conditions caused multiple crashes. All lanes were reopened about 7 a.m., though police cautioned ramps might remain slick.
Indiana State Police for the Lowell Post also responded to slide-offs and spin-outs on Interstate 80/94 throughout the morning.
A freezing rain advisory for Lake, Porter, Newton and Jasper counties and Chicago's south suburbs expired at 9 a.m., though the National Weather Service warned some slick spots might remain on roads. A freezing rain advisory for LaPorte County was extended until noon, according to the National Weather Service.
Sidewalks, driveways and parking lots covered in ice posed a risk to anyone walking.
A wintry mix of precipitation is possible during several weather systems expected through Monday morning, forecasters said. The additional precipitation could create a flooding risk.
