I wouldn't want to be waken up in the middle of the night to transfer from a train to a bus and back to a train.
Amtrak never operated to San Francisco, so the last train from LA to SF was on April Fool’s Day of 1971. For some reason I’ll never fathom, Nixon chose to create Amtrak instead of deregulating passenger rail to reduce their operating costs.
“The last time I checked, rail transport from Los Angeles to San Francisco involved some transfer to and traveling on a bus”
Yep, my Mother took the train from Fullerton to the Bay area a number of times. I’m thinking the last time was 20102 or there about. There was a train to train transfer and a bus transfer for part of the journey. Looking at current train tickets for this route, the train to train transfer is in Bakersfield and from Emeryville to S.F. it is bus.
