Rowdy rider assaults Caltrain conductors

An unruly passenger was arrested in Mountain View after she physically assaulted two Caltrain conductors Saturday night, a Caltrain spokeswoman said today.

At about 8:30 p.m. on Saturday, San Mateo County sheriff’s deputies responded to a report that a rowdy passenger had physically assaulted two train conductors on a southbound train,Caltrain spokeswoman Christine Dunn said.

Deputies arrived at the station and learned that a female passenger had been acting drunk and yelling profanities while aboard the train.

When train conductors asked the passenger to quiet down, she refused, according to Dunn.

The conductors then asked the passenger to get off the train at the San Antonio Station.

When the passenger exited the train and reached the platform, she swung her bag at a female conductor, striking her in the head several times, Dunn said.

A male conductor then approached the passenger and he was also assaulted in the same way, according to Dunn.

The suspect, identified as 22-year-old Mountain View resident Maria Posada-Valderrama, was transported to a hospital for an evaluation before being booked into Santa Clara County Jail for the felonies, assault with a deadly weapon and assault on transit personnel, the Caltrain spokeswoman said.

Dunn said the train was stopped for almost 30 minutes before service resumed toward San Jose.

The female conductor was later transported to a hospital for a head injury sustained as a result of the assault. She has since been released, according to Dunn.
