CTA supervisors and managers donned the familiar neon vests to direct passengers exiting from the trains at 55th street's Garfield station while service was halted.
"Yeah, I was like, oh, what was going on? They were just like I got to take this. And no more trains coming this way," said commuter Angela Crockett.
Buses will carry passengers southeast to the Green Line's 63rd and Cottage Grove stops-- and southwest to the 63rd and Ashland stops.
"They're going to be discouraged. Something as little as this triggers some people off," said commuter Cheryl Cates. " Some people are going to have bad attitudes."
The mishap is putting extra pressure on the Red Line, which takes people south along the Dan Ryan Expressway. No extra trains have been deployed there, however.
Traffic on the expressway is also likely to be heavy.
"We feel like we're the best in the world. And we do this all the time," said Lee Robinson, CTA supervisor.
