All aboard! Take a virtual tour of the new electric trains.

Construction Overview

Caltrain Electrification construction is occurring between the 4th and King Station in San Francisco and Tamien Station in San Jose. Construction activities include locating underground utilities, testing soil conditions, inspecting signal/communication equipment, pruning/removing trees, and installing foundations in preparation for the installation and operation of the Overhead Contact System that will power the new electric trains.

Work will be performed during the day and at night. In order to limit the impact to regular train service, night work will occur between 8 p.m. and 6 a.m. when there are fewer regular service trains.
