We need BART to come down the Peninsula. Roughly same cost as Caltrain/HSR with Grade Separations, `$12Bm. This will create a unified single Bay Area voice to lobby for funds, safer, single administration-with higher capacity x2 due to dual direction BART around the Bayeventually. Terminate HSR up the Peninsula, rather, if HSR cannot be stopped, then send it up to Oakland on East Bay--Capitol Corridor tracks, then to Sacto along busy I80 corridor, not through small Central Valley towns. The $1.5B for current Caltrain electrification could be better spent to extend BART south from Millbrae through Burlingame (aerial, trench or tunnel, as Burlingame wants) and into San Mateo...a step closer to closing the final 30 mile gap to future Santa Clara BART station and one unified, high volume, grade-spearated, more frequent, all Bay Area integrated, efficient and effective rail, not an expensive hodge-podge of Peninsula rail transit amalgamations.
