Dumbarton Express

This service operates as a commuter route operating via the Dumbarton Bridge between Union City BART and Stanford University in Palo Alto operating weekdays only, with frequent departures during peak periods (5:20am to 9:45am, 1:30pm to 8:45pm). It is operated as a consortium of five different agencies that serve both Alameda and Santa Clara Counties, namely AC Transit, BART, SamTrans, Union City Transit, and Santa Clara VTA, with MV Transportation as the operator of the service. The two routes include:

  • Line DB: Union City BART – Stanford Oval via Palo Alto Caltrain, Willow Avenue, and Ardenwood Park-and-Ride
  • Line DB1: Union City BART – Deer Creek Road (Stanford Industrial Park) via Page Mill Road and Ardenwood Park-and-Ride. Palo Alto VA Hospital served AM westbound and PM eastbound only. Operates from 6am to 9:30am and 1:30pm to 8:45pm.

Prior to December 2011, AC Transit was the primary operator of the service, with specially-marked Dumbarton Express buses (and sometimes, AC Transit buses) used on this Transbay service; now, it is operated by MV Transportation on behalf of the five agencies mentioned above. It uses Gillig Phantom city-style and suburban-style coaches (with air conditioning and WiFi on board).

Those Gillig Phantom buses have been subsequently replaced with the more modern and comfortable Gillig Advantage LF40 suburban-style buses, identical to those operated by AC Transit.

The following routes include:

  • Hollis (with service to Emeryville Amtrak Station and Berkeley Bowl in the City of Berkeley), which operates all-day weekdays only
  • South Hollis (same as the Hollis route, but operates between MacArthur BART and Emeryville Amtrak only), which runs weekday peak periods only
  • Watergate Express (express service between Emeryville Marina and MacArthur BART via I-80 and I-580), which runs weekday peaks only
Buses (35-foot, low-floored)
These are mainly used on the Shellmound/Powell route during the weekdays, as well as the Watergate Express service during the peak periods.
