UPDATE: Secret Service says rail lines will operate, but commuters should expect delays...
Could NATO summit security temporarily shut down train lines into downtown from Chicago's South Side?
It's a possibility, according to Crain's Chicago Business. Rail lines that run under McCormick Place, where the May summit will take place, could be redirected or suspended during the two-day meeting of leaders. Lake Shore Drive and the Stevenson Expressway near McCormick also may be affected because of tight summit security.
It was an issue pointed out back in February when Chicago thought it would get both the G8 and NATO summits. Even with just the NATO in town, rumors of transit troubles haven't let up.
Still, Metra officials could not confirm with NBCChicago any plans to shut down its Electric line, which runs beneath McCormick Place. Metra says it's working with the Secret Service and expects to hone in on details next month.
"At this time, key locations that will be impacted by traffic diversions or road closures are being identified," Metra said in a statement on its website. "We will address those issues as more information becomes available."
Similarly, the South Shore Line said it plans to update passengers about any transit changes when that information becomes available.
"While our police department is participating in transportation security planning with multiple local, state and federal law enforcement partners, there are no specific plans at this time to indicate how the summit may affect passenger service," the line said in a statement on its website.
The Chicago Transit Authority also would not comment.
The summit in Chicago will be held May 20 and 21.
