Double Deckers Are Rolling

actransit's double decker bus

AC Transit continues its commitment to improve Transbay service with the introduction of double decker buses. These buses are brought to you by Transbay Tomorrow, a visionary AC Transit project dedicated to reduce overcrowding and improve congestion on the Bay Bridge. The double decker buses will increase capacity to 78 passengers per coach with amenities such as Wi-Fi, footrests, reclining seats on the upper deck and three bike racks, while offering sweeping panoramic views of the Bay.

The first phase of the rollout included Lines FS and J, two of the highest ridership routes, serving over 1,600 passengers daily. The second phase brings double decker buses to Lines L and LA on February 11, 2019. These two Transbay lines serve over 1,200 passengers daily.

AC Transit brand ambassadors are available during the rollouts to answer questions and offer safety tips for comfortable rides. For further information, please refer to the brochures available on buses, review the FAQ section below, check out our Ridership, Bus Fleet and Service page, or call Customer Service at 510-891-4777.

AC Transit staff is very pleased to bring this dramatic improvement to Transbay service, and hope you will enjoy the double decker experience.
