City officials say there are now more than 1,600 cameras at 73 rail stations. And by this summer, all CTA stations will have high-definition cameras at the entrance.
Chicago police Supt. Jody Weis said he was very happy to have the cameras as crime-fighting tools.
"Our main focus is to put a deterrent in place, then have the capability to catch these guys," Weis said. "We can see crime taking place, and we can be waiting for them at the next stop. [It is a] huge benefit for us, and we will be waiting."
Federal Homeland Security funds helped pay for the cameras. Next, the CTA will look at retro-fitting all its rail cars with cameras.
