Yep, same reason, wheel seized up. It's still a VERY rare occurrence if the ride is well maintained.
Sorry for the double post, but in a launch situation especially it's very hard to get a ride to balance perfectly in a spot like that. It naturally would want to go one way or the other depending on the forces. Once again not IMPOSSIBLE, just improbable.
This has just gave me a flashback of Beverly Hills Cop 3. :faint:
If everybody on board was to sway their weight back and forth, nudging the train forward, would the brakes still work?
I know this seems like a really stupid question but are the brakes designed to work the second it senses a train passing regardless of how long has passed, or does it know roughly when it should expect a train coming.
Trim brakes, if I am not mistaken, are connected to a sensor and are merely for speed control. Holding brakes only catch on when the system demands it. I think most brakes function as both as well, so the midcourse trims excess speed and holds in case the course is not clear.
In theory (if everything is right) shifting the weight or even a gust of wind would get it going. As it was for TTD all they did was have a mechanic give it a push forward which is dangerous because when the train starts moving the could get pulled over with it.
The brakes are basically "always engaged" on a coaster so if there is a power failure it will stop. It''s only with power that brakes retract or release.
In Efteling, the Python coaster once got stuck, they opened the restraints to evacuate and then the coaster moved again, luckily everyone managed to close their restraints again.
I know any time I've seen them move a coaster that's valleyed, it's a slow process moving it a few feet, putting some kind of blocks on the track so it can't roll back, then moving a few more feet.

That was great!
Given how tightly packed into your restraint, I can't see this happening on a B&M with over the should restraints.

Maybe there already on the track. Done at night time when no one is in the park?

B&M don't do pull though they get the maths right on everything i watched a documentary on it, link below
I bet Universal does not rely on a computer to "get it right". If I were in charge of making sure the car and the guest didn't contact anything I want a mockup to physically prove it. Remember we sent a craft to Mars and missed due to a error in units.
In any case they have a ton of plumbing to run before anything goes out on the track. At least a month.

John Wardley once asked Walter Bolliger: "What if the coaster stalls? How will we get the trains back to the station?". Bolliger replied: "Our coasters never stall. They always work perfectly the first time."
I don't know of any B&M coaster that has ever had a pull through.

Dude these rides are tested extensively in modeling under a range of simulated conditions. Computer modeling and simulation is the difference between an Arrow ride and B&M. B&M (not Universal) tests this all. Pull throughs, if they occur, happen for several different reasons including clearance, water dummies, etc etc.
