Henner, Bruce MacGregor wrote several books on the SPC and they are a great source of information. SPC ran commuters from Alameda down to San Leandro and back, running the engine around the cars rather than turning. Here is a picture from one of his books taken looking west across the mud flats with an outbound 4-4-0. Note the link and pin couplers and pilots on both ends: SPC ran link and pin until it was standard-gauged in 1906. Here is another picture from a MacGregor book, this one of caboose #47 on the last 1906 cleanup train being pushed south through Agnew station, with its link and pin draft gear intact. I hope this helps. I'm a great SPC fan, but am now far removed from the Bay Area! Best regards, Alan |
