Commuter rail ridership broke an all-time record this week, and Caltrans reported a dip in freeway traffic as commuters across California struggled with record gasoline prices.

Metrolink recorded its highest number of riders in a single day Tuesday — 50,232 — a 15.6% increase over the volume on the Tuesday of the same week last year. Metro Rail ridership has also risen, shooting up 6% last month over May 2007, with the downtown L.A.-to-Pasadena Gold Line setting an all-time ridership record, said Dave Sotero, a Metro spokesman.
