Metra and Amtrak trains heading into and leaving Union station are now moving after being stopped over signal problems, according to a Metra representative.
Metra is advising that commuters stay away from Chicago Union Station if possible, due to concerns of overcrowding.
Commuters are being told to listen to platform announcements for delay times or refer to Rail-Time Tracker located on Metrarail.com for current delay information.
The length of the delays is not currently known.
