The Pepsi Max Big One's Reprofile?

Friday, June 13, 2003 11:43 AM
I was just cruising Joyrides website and was in the Blackpool Pleasure Beach section and saw a pic of the Big One that said it was reprofiled in '97 by Allot and Lomax to provide a smoother ride. What parts of it were reprofiled does, does anyone know? Here's the link: http://www.joyrides.com/bpb/full/big_one.htm

Plackpool?! I know people were pretty upset with Pontin's, but that's not a very nice way to put it back at them. ;)

I know, that's not A (emphasis on "A," if ya get what I mean) very nice way to put it. Before you correct my grammar and spelling correct your own.

Did you stay at Pontins Danny? I did on the ECO and was not upset at all by it. Some people didn't like it and some people did. Don't say something like that unless you were actually there.

As for the reprofile, if I'm correct the first drop was reprofiled in '95? and the far turnaround was reprofiled in '97. I'm not 100% sure, but it did go through several reprofiles the first 5 years of its life. It's first drop is still wicked.

DD- I was kidding. The wink just doesn't do it any longer. That's not to mention the three mistakes in your last post (ya, its, break).

CK- I said "people", which doesn't mean "all people" or even "most people". I apologize for your confusion, but "people" still stands as you yourself said, "Some people didn't like it". Six Flags Over Texas has a coaster named Titan. I've never been there though, so maybe I shouldn't have said that.

-Danny, joking, continuing comedy week on CB (thanks LG), and wondering what Mr. Freeze would say about this (no corrections requested)

Back to the original topic:

The first drop was reprofiled to remove the sudden twist to the right near the top of the drop. Although I really enjoyed this aspect - it made you feel even more out of control 'cos it flicked you sharply to the left (and there's nothing at all to the left of the train except the park below) - it started to create stress fractures in the track - not good! The train now rolls to the right around a point closer to the centre of mass of the train - it used to rotate with the track at the centre of rotation, hence the lateral forces.

The other reprofile took place at the turnaround over the Grand National. This was not a smooth cureve, but more like two left turns with curved track between them - if that makes sense. The train was given two sharpish jolts to the left as it turned. The new turnaround is actually inside the support structure at the start of the turn, rising up to the top of the structure by the middle of the turn. This has reduced the radius of curvature of the first part of the turn, and keeps the train going slightly faster.

Although I miss that sharp twist on the drop, the rest of the ride was much improved as a result, and now the hills on the return run are taken faster, with better airtime than before and a better overall ride experience. Plus, it is much smoother than Magnum!

This pic shown the reprofiling of the turnaround, making a tighter bend. You can see the square bases under the red track that attach to the supports. The supports have been extended to. On the outside of the bend you can see the unused bases where the former track was, on unextended supports.

This pic of the 1st drop shows how the twist was widened. You can obviously see where the track is now, but you can also see where the supports have been extended, and therfore make out where the former track was.

Incidentally, some of the replaced track was used to support Valhalla's facade, pic here, & the Spin Doctor entrance! The rest of the track is at Pleasureland in Southport awaiting recycling!
