Is there an issue with Alpie's Cobra roll kicking crap to Nessie?
Seems like a cheaper and less distracting solution would be adding netting to Alpie's track like exists in other sections than to add a structure to Nessie.
Methinks this is more to do with covered train storage as others have suggested. I too hope they match the style and color of the station or at least make it look like a natural extension and not a cheap addition.
Yes, someone got hit with a phone from Alpengeist while sitting on the track waiting to go in the station last year. Along with the budget going into theming, it was proposed to simply build a net on the Loch Ness transfer track. It went through a lot of changes before becoming what's actually happening. It knocks out three birds with one stone actually. You've got extra theming, protection for guests from Alpengeist, and now new covering for the trains during the season. Also, new lights outside and cover for easier inspections for the mechanics every day.
I wouldn't expect anything grand for the building itself. I'd think it'd be more similar to the little buildings in the extended queue.
