January 22, 2013 > BART subject to late night delays in the Transbay Tube BART subject to late night delays in the Transbay Tube Submitted By Alicia Trost BART continues to make its system safer in the event of an earthquake. This week BART began work to complete a power supply upgrade project in advance of the next stage of its Earthquake Strengthening Project. There will be some late evening work in the Transbay Tube for the next few weeks which will require use of only one track after 10 pm. This work is being scheduled during hours that will minimize disruption to customers. Work must begin during passenger service hours because it requires more than the 2-4 hours each night that are usually available for servicing the Transbay Tube. Customers traveling during this period should allow extra time as trains must share one track between Montgomery Station and West Oakland Station. BART will try to minimize delays and will maintain transfers for customers making connections between lines. On the evenings that the work is performed, BART Service Advisories will keep customers informed. BART appreciates its customers' understanding as the system is improved. The work is scheduled for the following nights though the schedule is subject to change: 1/21, 1/22, 1/23, 1/24, 1/27, 1/29, 1/30, 1/31 and 2/5. The next phase of strengthening work in the Transbay Tube will begin in the first week of March 2013 and continue for 13-14 months. This work also requires single-track use during late night hours.
