I also noticed that in the architect’s drawing all people are shown with no luggage. What is the chance that people moving around Central Valley aren’t carrying half a ton of stuff with them all the time? If they aren’t carrying anything, why they are even going themselves? Those trains seem to be useful only for office workers (and only those who can’t live near work.)
The only use this really has is in replacing the plane traffic from los angeles to san francisco. that would make sense if we were facing major airport congestion on either end, but I don’t think that BUR, LAX or SFO are in bad shape. OAK’s line for southwest can get ugly, which is why i use business select.
it would be more interesting to see if it takes seasonal commuters off of the 5 - i.e. students, but there can’t be enough of them going between the bay area and LA to make an appreciable difference.
