I remember back in 2004 I think it was, one of the cable cars got jammed as it was coming off the cable onto the cadence rail which guides it into the station, coming from Ugland into the FV station. Not only was there a risk of the car coming off altogether (with people in) as it was neither on the cable of cadence rails, the jam brought the whole system to a full stop.
I believe it was in the middle of June, so if something like this happened again, post Smiler, I think Alton would want to avoid it at all costs.
