Thx for interesting comments... seems early on the OAB 400 500 & 600 series cars carried such lettering as CP and SPC and perhaps other lettering down by the gates. All some 5 tracks in the Ward St yard had overhead but during the 30's passenger cars were not seen there by daylight at least after the Ellsworth abandonment.... The Berryman or Rose St yard wss usually vacant all day...but full at night and weekends. Football specials waited there during Cal-Stanford games. I believe there were not less than 5 if not tracks.
