Single Tracking Alert: Late night rail work on the Yellow Line in Contra Costa County (December 4-6)

(Updated 11/19/2025): The late night work that had been planned for November 20-22 has been postponed due to weather. The work is now scheduled to resume December 4-6.

BART is performing rail destressing on the Yellow Line in Contra Costa County. To create a safe work space for our crews, BART will reduce service from two tracks to one while the work is taking place. The work is scheduled to start at midnight and continue until BART service begins the next morning. Riders can anticipate delays of 20-25 minutes on work nights. The next location for this rail maintenance work is between North Concord and Pittsburg/Bay Point stations December 4-6.

Dates scheduled for this project include:

*December 4-6

*December 18-20
