The annual Caltrain Holiday Train, decorated by volunteers and sponsored by corporations and businesses, operated December 1st and 2nd.
The train begins at San Francisco and makes specific stops at peninsula stations, with a different set each night.
I went to two stations, San Mateo and Sunnyvale, on Sunday the 2nd. You'll see offside shots of the train at San Mateo and business side photos at Sunnyvale.
