We had this happen to us last time we were are SFOT. We were sitting front row of the train, it came back into the station, and stopped short. Maintenance came in, and seriously moved the train forward a few feet. That reset everything. A few minutes later the track slid sideways and we were able to exit the ride! Sadly the entire process took about 25 minutes mainly because maintenance took forever to show up. Once they were there it took about 5 minutes to get everything fixed.
