I started chasing the Santa Cruz Local around 1986, and they "always" ran Monday/Wednesday/Friday, on duty at Watsonville Jct. (later Salinas after SP gutted WJ), on duty at 0600. I last chased it in 2010, and UP was basically still doing the same thing, although the on-duty point had reverted to WJ (and Salinas is now dead as a doornail). I understand that back when it was a 5-6 day job, they ran from Santa Cruz to Olympia (on what is now the Santa Cruz Big Trees & Pacific) on the alternate days, but that was before I arrived on scene.
