Riding without a ticket? Jail.
Littering on the platform? Straight to jail, right away!
Doing any violent crime in NK transit? Believe it or not - death by firing squad.
Here is a quick overview of how the system works: https://youtu.be/eiyfwZVAzGw?si=CnOMa8F6NkiyhifE

It seems to me that they are over-worked & under-paid and are doing a good job given the circumstances.
NIMBYs have blocked BART in Silicon Valley. BART doesn't reach Menlo Park, Palo Alto, Stanford, Mountain View, Sunnyvale, Los Altos, Santa Clara, or Cupertino. A few years ago, it finally reached San Jose.
A separate train (CalTrain) goes from SF through Silicon Valley. Last year they switched to electric trains which are faster and run more frequently. The SF CalTrain station is inconvenient (20-mins walk from downtown, under a highway), but they are working to extend CalTrain to the central SF station: https://en.wikipedia.org/wiki/Salesforce_Transit_Center#Futu... .
So Silicon Valley transit is getting better, slowly.
Setting aside safety for a moment, consider just hygiene: BART is shockingly dirty. Which suggests mismanagement, above and beyond just a lack of detterence of criminality.
As for safety -- firing squads are probably not in the cards, but would jailing the violent be too much to hope for?
