FOX 32/SUN-TIMES MEDIA WIRE - Extensive delays on three Metra lines were expected to persist through the night after signal problems prevented any trains from entering or leaving Union Station during the Wednesday evening commute.
Trains on the BNSF Railway, Southwest Service and Heritage Corridor lines were stopped in and outside Union about 5 p.m., according to the transit agency.
"At about 7 minutes before 5 o’clock tonight, we had a failure of a key switch in the yard that malfunctioned," said Marc Magliari of Amtrak.
By about 6:30 p.m., the signal failure — which Metra said stemmed from Amtrak signal issues — was fixed, Metra said.
Riders should listen to platform announcements or check their routes online, Metra said.
Riders were also, obviously, upset.
“A little unhappy, grumpy, just want to go home,” said Sherri O’Slick.
"I have never witnessed this in my life. I was born and raised in the city so this is an exodus, I call it the exodus,” said Anu Yedavalli.
"There is no good time of day for these kinds of problems to develop with the infrastructure. Tere are probably not a lot of times worse than 5 p.m. on a weekday," Magliari added.
