Caltrain has begun performing pre-construction work for the Peninsula Corridor Electriﬁcation Project. Until the end of February 2017, the San Francisco-area commuter railroad will locate utilities, conﬁrm soil conditions and test cables in preparation for the electriﬁcation project, which will electrify Caltrain’s corridor from San Francisco’s 4th and King Station to approximately the Tamien Station. The railroad also will replace its diesel-hauled trains with electric multiple units. The project team is slated to begin construction in summer 2017, according to a Caltrain press release. The overarching project calls for electrifying Caltrain’s corridor from San Francisco’s 4th and King Station to the Tamien Station in San Jose, Calif., along with replacing the railroad’s diesel-hauled trains with electric multiple units.
