Reports of serious crimes on the CTA rail system have doubled since 2015 even as ridership declined and such crimes rose only slightly citywide, according to a Tribune analysis of Chicago police data.

At the same time, the arrest rate for these “L”-related crimes has dropped, suggesting that even as CTA’s rail system has become more dangerous, there is less chance the perpetrators will be held accountable.

The troubling trends have occurred despite the CTA installing tens of thousands of security cameras that city officials have credited in the past for reducing crime on public transportation.
