BART just released video of its announcement of major delays this weekend and next because of the closure of one track through the Transbay Tube due to repairs.
Specifics in the video:
Or, if text is more your thing, here it is in black and white:
On the following days in May and June, there will be major delays for some customers traveling through the Transbay Tube due to vital maintenance and repair work. The delays are necessary to accommodate work on the cables that provide power to the track. Our best estimate is that delays for trains in both directions will be approximately 20 to 40 minutes on the lines requiring transfers (trains coming from or going toward Dublin or Fremont) and 5 to 10 minutes on the other lines (trains coming from or going toward Richmond or Pittsburg/Bay Point) during the hours listed below.
During the hours listed below, customers who are traveling from any San Francisco or Peninsula station toward Dublin or Fremont will need to take a Pittsburg/Bay Point-bound train to travel through the Tube. You will need to get off the train at 12th Street Station in Oakland and go downstairs to transfer to a special Dublin or a Fremont-bound train.
During the hours listed below, customers who are traveling from Fremont or Dublin to San Francisco and Daly City will need to board their usual train. These trains will be diverted to MacArthur Station. This diversion is necessary because the trains originating in Fremont and Dublin during the hours work is performed will not travel through the Tube. Customers should get off the train at 12th Street Station in Oakland and go downstairs to transfer to a San Francisco-bound train.
