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.
Monthly Construction Update
Each month, we are getting closer to Caltrain Electrification. Check out August's progress below. For more detail on construction progress by station, see the table below for a snapshot on how close we are to bringing passengers greener, faster and more frequent service!
