It may be possible that some problem unrelated to the incident earlier this season was detected. The slightest malfunction can cause grave attitudes until the real problem is known. For instance, the air canisters for the station brakes on Blue Streak. We knew one was leaking, and were kinda edgy about it, but maintenance reassured us that everything was fine. The worst that could happen is a train not being able to leave the station, because the air opens the brakes. A loss of air pressure simply meant our brakes wouldn't open, which wasn't a real safety concert.
Unless maintenance finds something major that can't be fixed by the weekend, it will most likely be up and running.

Three things you need to fix anything in the universe: duct tape, WD-40, and a hammer. Duct tape if it moves and it shouldn't, WD-40 if it doesn't move and should, and the hammer as the last resort.
