Let's not get into this, (then gets into it) but the ride is being destroyed in its current form, melted down etc. So, using the word demolition is correct, so is dismantling, but dismantling can imply it will be used elsewhere, it will not be. So yeah, it's being demolished, as it will be melted down and used in a new life. Demolishing something does not just mean you remove it from a site carelessly, it can mean other things too.
But I would argue that it is a majority but partial demolition, as the lift, break and station track are staying. The fact the track is sitting on the tarmac in the carpark is a big no no for careful handling of track. Very easy way to do damage. So, in essence they are carelessly removing it, in line with a demolition. I mean you do not think they are going to use steel cutters and what not to remove the track? In this case it is far easier to just remove the bolts away, it would make the job harder cutting it all up from it's location.
In other news, you can really see how bad the state of the track is from a presentation perspective at least, when removed from the pit. Roll on the brand-new B&M track!
I agree but, seeing as Alton has one of the strongest coaster line ups in Europe, it would be nice to sort of show this off, by adding more track to the entrance.
