New clue in that article; the trains will be on display not just at Oktoberfest, but also Christkindl Market. Since trains are on display on the tracks, parked for people to tour, this means that a train will be parked on the route during the Market, and thus service can't have started during the Market, so opening day will not be earlier than December 10th (market runs December 6-9).
