I don't really see that practice at Knotts however Magic Mountain does it all the time even when the place is packed. Knott's coasters such as Hang Time has three cars on the track. Silver Bullet, Ghost Rider, Excellerator and Jaguar have two. Obviously Montezuma only has one. I can't see them operating more than that. The rides aren't designed for it.I'm glad that Knott's and CF are doing well. That usually ends up being good news for most everybody.
But, one of the things that always seemed to stand out to me when comparing Disneyland to Knott's (and Magic Mountain) was their comparative ride throughput. (Disclaimer - I haven't been to Knott's or MM in well over 5 years) It seemed to me that both those parks constantly ran coasters with less than optimal number of operating trains, leading to longer wait times. Part of it might be due to the ride design itself. Montezuma's Revenge is clearly only going to run one train , and other coasters likely don't have as many brake blocks as a ride like Space Mountain, Big Thunder or Screamin'. Otherwise, I suspect it's due to keeping down maintenance costs by running fewer trains less often. It always kind of irked me waiting in line seeing one train dispatched, with no train waiting to roll into the station to replace it.
Is this still the typical M.O.?
However over at Magic Mountain, you always see things like Goliath, Riddler's Revenge and Batman have one train on the track. It still takes the employees 4-8 minutes to load/dispatch each train. There seems to be a lot of waiting between people getting on and dispatch. That kind of thing made me mad at Magic Mountain as I watch employees more interested in talking to each other than dispatching trains.
Disneyland's coasters are designed for a large number of trains at the same time. You never see this at other parks. They dispatch trains ever thirty seconds or so. It's pretty amazing. That is the kind of thing I wish I could see more of at other parks. Why can't coasters be designed for 3-4 trains at the same time? Even Chase the Baby can do four trains at once.
