Here is some interesting data gathered from recent testing of gate latching at the Normandie, North Hollywood and Western stations on the Red/Purple Line subway.
The takeaways: 1) one-way fares, stored value and pass sales significantly increased when the gates were latched; 2) Free entries — i.e. mainly those not paying fares — dropped significantly when gates were latched.
Metro staff continue to work toward starting to latch the gates in the Red and Purple Line subway this summer. As part of that effort, paper TAP tickets are being tested for Metrolink passengers who transfer to and from the Metro system.
