There is exactly one switch at Cannon, diverging from the UP to the former SN. The crossover between the UP mains is long, long gone. There is no siding there, and the wye to the Vacaville line came out with the rest of that branch. The other two legs of the Dozier wye (which were a boon to museum operations) were lost when the line to Libfarm was torn out in a case of Nero fiddling while Rome burned. It's interesting to note that the line from Rio Vista Jct. to Dozier--which for several years hosted diesel-powered passenger trains that contributed major revenue and public exposure to the museum--is now virtually abandoned. The explanation from the ruling cabal was that "nobody wants to work on that operation anymore." Considering how many members (many of whom put a tremendous effort into that operation) have left in disgust at the high-handedness and duplicity of the Tram Nazis, it's no wonder.
