BART has been quietly cracking down on fare evaders.
Since September, the transit agency has been conducting sweeps of morning trains out of the Embarcadero Station in San Francisco. Fare inspectors and BART police officers have been asking riders to show proof of payment. Those who don't have proof have been booted from trains.
BART says that during each sweep, between 75 and 100 riders have been booted.
When asked if the transit agency will be conducting sweeps at other stations, BART said it wasn't its practice to announce the time and place of its enforcement actions.
Fare evasion costs BART as much as $25 million a year, according to the transit agency.
