Obviously this one has some temperature problems. Typical for mid-rear-engine cars. Hopefully the two girls will get some help, soon. I love the idea of using ice scoops as smoke. I've seen that on several other fan models.
The color is named dark-purple. It's the same color, Harry Potters Knight Bus (4755) is made of. Lego had some problems with wide varieties within the bricks, so they decided not to make any further sets with dark-purple as main color. How sad, it's such a nice color, isnt't it?
The photos have been made, during the Legoland in Windsor was closed for public. The London bridge is seriously one of the best models in the miniland.
