Starting Monday, Metro Transit will begin tougher fare enforcement. Community Service Officers will begin asking riders for their fares. Those who haven't paid will be issued a citation. Fines start at $35 for a first violation to $100 for a fourth. It's part of a push to clean up light rail platforms and trains, and bring ridership back up. Part of that also includes a new rider code of conduct, which will be voted on December 13th. Metro Transit General Manager Lesley Kandaras joined MPR News host Cathy Wurzer to talk about the changes and how fare enforcement impacts rider experience.
