UPDATE: As of late Tuesday night the woman's condition improved, but she remained in critical but stable condition, according to Caltrain spokesperson Jayme Ackemann.
A female pedestrian struck by a northbound train at the Palo Alto Caltrain station on University Avenue Tuesday morning is still alive and has been taken to Stanford Hospital for treatment, according to Caltrain officials.
Northbound Caltrain #143, which left San Jose at 11:10 a.m., struck the adult female at 11:45 a.m. The train was headed to San Francisco.
The woman, a Palo Alto resident, was conscious and breathing, Caltrain spokesperson Jayme Ackemann said.
The train, which had about 200 people on board, was stopped at the scene and caused delays through the area.
Train service was shut down in both directions. One track was reopened at 12:20 p.m., and full service resumed at 12:45 p.m., Caltrain officials said.
