quit beating the dead horse, especially as you admit you are unaware of the history
One more time, as one who read the papers and listened to interested folks in the Bay-areheea at the time

Bartgage arose from two concerns

If standard had been chosen the 'lure' of faster transit would have been tarnished
"wait didn't we just get rid of the Key system?"- Yes and for good reasons.
Rebuilding a slooooow system made no sense

'High winds on bridges'
Berkeley got 'Linear Parks. BFD that that Bart runs above -eeeeewwwwwww eyesore.
If Berserkely wanted tunnels or? I don't recall any offers to pay the difference.

South of San Francisco the counties opted out of BARTD account "we have good old SP"
They , as the saying goes, made their bed

The std gage ebart is dumb- please show us an honest cost examination comparing the costs of incompatibility, such as odd equipment requiring and additional maintenance facility against the cost of longer prestressed concrete tie- or if one wanted to scrimp, longer timber ties

What ? you think Bart should be able to haul intermodal?? Dirty Dirt? Teslas?
Maybe livestock such as the SJV HSR orphans are doomed to do?

Please get a coupla new conspiracy obsessions. We've heard it all about @#$%& Bechtel, Tejon Ranch blah blah blah
