Below is an archived version (September 2005).
Page from the report "Preliminary Studies for an Additonal Bridge
Across San Francisco Bay", California Dept. of Public Works,
3/31/47.
It states that "approximately half of all transbay passengers are
carried in electric trains or busses." This figure is the total for
both off-peak and commute times. My calculation is that during the
critical commute periods, 2/3 of bridge users take electric
trains.
