 And the South Shore Line is looking for riders to take a survey to address concerns and take suggestions. They issued a letter in response to recent issues they've been facing with service disruptions. The most recent disruption was caused by a gas leak. In the letter, they explained that they looked to minimize the disruptions, though busing around the gas leak was not an option due to a lack of drivers available. They say riders were given the latest updates from NIPSCO, though times provided seemed to be overly optimistic.
