CHICAGO (CBS) — Normal service has resumed on the Red, Brown, and Purple lines, about three hours after a man’s body was found on the elevated CTA tracks near Fullerton.

Police said the body of a man in his 40s was found on the tracks just south of the Fullerton station around 6:30 a.m. The man was pronounced dead at the scene, and detectives believe the man committed suicide.

CTA halted trains on the Red, Brown, and Purple lines from stopping at the Fullerton station while officials investigated and removed the body from the tracks. That caused major delays for all three lines, and resulted in very long lines for buses that stop at Fullerton.

One good Samaritan headed over to the Fullerton station to offer rides to CTA commuters, and his Acura filled up in seconds.

“I just heard about all of the problems here, and I saw the crowds, and I just wanted to come over and try to help people get downtown,” Bob Thomas said.

As commuters scrambled to board shuttle buses provided by the CTA, or find some other way to get to their destinations, some were left choosing between being very late for work or paying surge prices for a Lyft or Uber.

“I’m going to wait for the bus. I told my boss I was late, and that the Ubers are like $50, and I’m just like, ‘No, I don’t want to go to work that bad,’” Dominique Wilburn said.

Around 9:30 a.m., the CTA announced normal service had resumed on all three lines. However, the agency warned there would be residual delays while trains began running through Fullerton again.
