My main concern about operations is Nemesis Inferno.
When I visited in mid-August, it was running on one train, advertising a 15 minute wait early morning. I ended up queuing 45mins max, only to add a second train as I got off [emoji14]
When I returned several weeks later, they where running two trains all day. Except that train two stacked on the block in-front of the station for up to a minute. Funny, that Alton Towers can dispatch their shorter Invert, even though it has longer trains.
Another reason why original Nemesis is better.
