Here is a list of options for linking Livermore to BART's Dublin-Pleasanton station that will be studied as part of the environmental analysis:
$55 million -- Enhanced bus feeder service.
$240 million -- Express buses with direct transfers at the BART platform.
$2 billion -- Diesel train system similar to eBART in East Contra Costa County from Greenville Road to the Dublin Pleasanton station.
$1.2 billion -- Full BART five-mile extension from the Isabel Avenue exit along Interstate 580.
$3.2 billion -- Full BART 11½ mile extension to Greenville Road with a station at Isabel Avenue.
