Normal Red Line service now restored with up to 10-car trains

5/6/22 Update

Longer trains are once again running on the Red (Richmond to Millbrae + SFO) and Orange (Richmond to Berryessa) lines following ongoing cable replacement work between the Richmond and El Cerrito del Norte stations. In early March, BART experienced a cable fault that forced us to operate train service at modified levels with mostly five car trains.

Earlier this week BART crews energized a new cable between the Richmond and El Cerrito del Norte stations. After several days of testing the new cable with ten car trains the determination has been made the new line is stable. While additional cable work will continue along the Richmond line, we are now able to restore normal operations with long trains.

BART had been working aggressively to replace its aging traction power cables before the incident in March and that work is continuing now with even greater urgency. So far BART has replaced 46 out of approximately 103 miles of 34.5kV (kilovolt) cable across the system. The new cable is vital to ensure trains have a reliable source of power. This effort is one of the key initiatives supported by Measure RR, which is the voter-approved bond measure that provides $3.5 billion to rebuild BART’s 50- year-old core infrastructure.

We want to thank our riders for their patience during this critical infrastructure work.

3/21/22 Update

Beginning Tuesday, March 22, 2022, BART will restore Red line service between Richmond and Millbrae. Red (Richmond-Millbrae) and Orange (Richmond-Berryessa) line trains will run with five cars. Restoring the Red line will help alleviate crowding by offering more frequency and by eliminating the need to transfer to the Yellow line for transbay service, despite running shorter trains. BART will continue to run five-car trains while crews repair and replace power cables.

Both the Red and Orange line will run the regular published schedule including Red line trips to SFO via Millbrae.

Five-car trains will stop at the center of the platform. Red and Orange line riders are reminded not to wait at the ends of the platform.

Damaged power cable

Earlier this month, BART lost power along portions of the Richmond line due to a break in the original 34.5 kV power cables that were scheduled to begin replacement the same week the damage occurred. Train service through the area is currently drawing power from redundant substations in the system. This break in cable limits our ability to run full service on both the Red and Orange lines with 10-car trains. Over the weekend, crews successfully tested the option of running shorter trains using current power levels available to us.


Orginal post from 3/8/22

BART service between Richmond and MacArthur stations is limited to Orange Line service only due to power issues experienced in the section. Currently there are no Red Line trains in service. This service impact will be in place for a few days as crews work continuously to mitigate the issue and restore service. 

Orange Line trains will be running a normal schedule. Riders between Richmond and Ashby stations can expect a train every 15 minutes in both directions on weekdays until 8pm when trains run every 30 minutes. On weekends, trains will be arriving every 30 minutes in both directions on the Orange Line. 

If riders between Richmond and Ashby stations are traveling to/from San Francisco/SFO, they will need to transfer between an Orange Line train and a Yellow Line train:

  • If traveling TO San Francisco, riders can expect a timed transfer between an Orange Line train and a Yellow Line train at MacArthur Station
  • If traveling FROM San Francisco, riders can expect a timed transfer between an Orange Line train and a Yellow Line train at 19th St. Oakland Station

Due to no Red Line service, BART will be providing a shuttle train between SFO Station and Millbrae Station. If traveling to SFO from the East Bay, please take a Yellow Line train, which provides direct service. Currently, the Trip Planner does not reflect the addition of this shuttle train.

Riders between Richmond and Ashby stations who wish to skip the major service impacts can bike or take AC Transit buses, which connect at multiple BART stations. The following connecting bus routes are:

  • 72M (Richmond, El Cerrito del Norte, El Cerrito Plaza, North Berkeley, 19th St Oakland)
  • 72R (El Cerrito del Norte, El Cerrito Plaza, North Berkeley, 19th St Oakland)
  • 72 (El Cerrito del Norte, El Cerrito Plaza, North Berkeley, 19th St Oakland)
  • 6 (Downtown Berkeley, MacArthur, 19th St Oakland)
  • 18 (Downtown Berkeley, MacArthur, 19th St Oakland)
  • 51B (North Berkeley, Downtown Berkeley, Rockridge)

Riders between Richmond and Ashby stations may also choose to park and ride at MacArthur, Rockridge, or West Oakland stations, which are unimpacted and have parking lots. All three stations have parking capacity currently.

What the Issue Is

On Sunday, March 6, 2022, BART experienced a power traction cable fault (or break) between El Cerrito Plaza and Ashby stations. While Orange Line service has been restored, the damaged cables are unable to feed enough electricity to run additional trains at this time.

On Monday, March 7, 2022, BART experienced a substation failure in the same section which led to power loss between El Cerrito del Norte and North Berkeley stations in the morning. While the substation failure had great impact on Monday, staff who are responding to this issue have concluded that the cable fault is the main culprit of the service impact. BART has sufficient redundant substations in its system to be able to distribute electricity to different parts of the system in need, and thus the substation failure is not a critical issue.

The damaged cables are part of the original 34.5 kV cables which BART has been replacing systemwide for years. The cables were installed in the 1970s as part of BART's original infrastructure and have outlasted their useful life 50 years later. Cable replacement work has been ongoing in both San Francisco and in Alameda County as a major part of voter-approved Measure RR rebuilding work. The cables will be replaced with latest generation cable technology, which can reliably feed electricity to trains in service. In a stroke of misfortune, this section of cables were to begin replacement on March 10, 2022 -- just four days before its damage created this service impact.

Currently crews have located the cable fault and are working to restore service as expediently as possible. However, due to the severity and complexity of this repair, crews may need extra days to fully repair the issue so BART riders can expect a more reliable ride in this section for the foreseeable future. 

BART is also exploring running shorter trains (around 5 cars per train) at much higher frequencies to alleviate the service impact between Richmond and MacArthur stations.
