Just saw a post by a friend over on Train Orders Passenger Board regarding CS detours over the weekend of September 7 - 9. Indeed, trying "test" bookings LAX to SBA and return #14 shows "sold out"; LAX to SAC shows the usual options. Pacific Surfliner trains show various Thruway Bus/Pacific Surfliner combinations for the same routing. Being somewhat familiar with the Metrolink Ventura Line to Chatsworth, I know several new signals have been "waiting" to be cut in; mostly around Van Nuys. Might be an opportunity to travel the Tehachapi Loop! I don't have info beyond what I presented here.
