How does a coaster chain break? I've never heard of that before, not saying that it couldn't happen though, I'm not an engineer.
What I have heard of fairly frequently though is a chain lift hill gear box breaking as described above.
It can happen just through wear and tear I guess, good preventative maintenance should stop it from happening though. If there was a manufacturing defect though, that could cause it to happen.
The trademark tapping sound you hear when going up a lift hill, is in fact the anti rollback system working, which would stop the train falling backwards if the train was to stop or the chain was to break. Although, the sound is dampened and or non existent on modern coasters as they usually use a magnetised centrifugal based clutch on the train, which pulls the anti rollback dog up from the anti roll back rail when the train is in motion.
