Construction Overview

Caltrain electrification construction activities will take place between the 4th and King Station in San Francisco to 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.
