The repairs, which start today and involve replacing power cables that are over 40 years old, will take place Monday through Friday and will cause delays of 20 to 30 minutes between South Hayward and Fremont Stations. The work is expected to be completed by September 9 — ahead of October, which BART officials say is their busiest month.
Bay City News notes that the work requires officials to single-track trains between South Hayward and Fremont, and that that is what's behind the expected delay.
"Passengers heading to Fremont from San Francisco may need to transfer at South Hayward to complete their trip," reads the BART announcement. "Passengers traveling in the Fremont to Richmond direction will have to take a Daly City train from Fremont and transfer at South Hayward or Bay Fair to a Richmond train. Passengers who are traveling between Hayward and Fremont may wish to use the AC Transit 99 service to avoid delays."
This work is separate from another repair project that is shutting down track between Glen Park and Daly City for a number of weekends through mid-October.
