People who rely on the South Shore trains to get to and from the Chicago area will need to make other plans. The South Shore is suspending all train service both east and westbound because of blizzard-related damage. The winter storm knocked out power to several key parts of the train system last night, including at crossing warning devices.

The outage caused delays for South Shore rush hour trains.

Train service cannot be restored until NIPSCO repairs the circuits and re-establishes power to those crossing warning devices. Passengers can use their South Shore tickets on Metra trains until the service is restored.
