A water main break at Union Station caused problems for some trains and commuters at the start of rush hour Friday afternoon.
Metra said it was advised by Amtrak personnel that a water main breakage on the South Concourse resulted in water leakage in the area.
Maintenance workers were at the scene and were “working to correct the issue.”
Metra and Amtrak officials said they were assisting riders looking to take BNSF, Southwest Service and Heritage Corridor trains. The issue was affecting tracks No. 6 and No. 8, officials said in a service alert.
“Once the issue has been resolved we will provide updated information,” Metra said.
Riders at the scene complained of a "waterfall" of water and said the leak had a distinct smell. Water was seen pooling on the ground in the area.
"I just stepped into this like puddle of water and I look up and there’s just all this water falling down," said rider Jake Bailey. "Water was falling on top of me as I was walking down the stairs."
Officials were seen turning people away from the area at the station. Those who would normally board trains in the area were being sent to other tracks.
