I think the park don’t really know what to do for a Christmas event.
You only got to look at Paulton’s on how to operate a Christmas event with roughly 75% of the park open.
Even Drayton increasing there Christmas ride line up with Frontier Falls (minus the haunting) been open as well as Thomas land.
true, but a lot of the rides being open are lower force and complexity compared to Alton.
The reason the park closes over winter is for maintenance to be preformed on all the rides and typically they will have to do many things, for parks with a lot of rollercoasters (such as alton) this will be a long list of things, worsened due to the fact the have 2 very complex rides (Gal and rita).
for ryan the ride mechanic (
From: https://www.youtube.com/watch?v=cCws2gu55s4
) each rollercoaster needs:
Anything that moves on the track is torn apart and inspected and refurbished. (lift gearbox, chain, breaks, booster wheels (including gearbox), air gate hardware, station hardware, contactors, compressors etc.)
someone has to go around and manually inspect the entire track, via boom lift, crane etc.
The trains also have to be refurbed, tearing it down till there is nothing left, inspecting and then reassembling it including: NDT on the chassis, pins the wheels are checked and replaced if needed, wheels bearings are checked. all the restraints are checked and inspected. then it is reassembled.
Then they load test the train to allow the bearings to bed in (to put it simplistically)
Then block testing.
and possibly some extra inspections.
Needless to say this all takes a while, and for smaller rides with less vehicles and ride hardware it can take less time.
