If power is cut to the whole attraction, it's an E stop.
If the attraction closes, it's a 101.
If there's an issue at load/unload and the cars are stopped there, it's a station stop.
But what about the rides that are on a continuously moving belt (HM, Buzz)? When there's a problem, all the cars have to stop. What's the term for that? It's not technically a station stop, since they're all stopped throughout the attraction, but the situation's usually only temporary (for example, to load a wheelchair party), so it's not the same as a 101.
