At the frequencies being talked about double tracking stations and adding a few more passing sidings will prevent limitations from that source for quite a while. Remember, the first limitation they have is lack of staff and after that lack of equipment. After they solve those they can worry about track capacity.
Electrification may (and I say may) be implemented differently. Solid electrolyte batteries are a subject of intense research. They allow solid metal electrodes that increase the capacity two or three times, are not flammable, have a high charge rate and seem to have a very long life. If they actually come to be, one could have a few hundred yards of catenary at each station and recharge during the end of deceleration, loading and the beginning of acceleration.
If the batteries are as long lived as is hoped there could be batteries at the stations to even out the peak current requirements on PG&E.
Speculation? Of course but:
