i started to visit miniatur wunderland in hamburg about 3 years ago and visit once a year now because they keep on building and extending it. the matterhorn is now ready and iv yet to see that and cant wait.
the control system for it couldnt just run british rail, it cud run europe lol. there is a room for the computers and also a glass case to show the actual computer boxes all whizzing away. id hate to think about the planning for the electrics of the place and everything else in fact, only the germans could build a model railway to this level of detail, size and complexity.
if anyones interested, i cud post up the pics i took when i was there. my favourite scene is the long hi speed line over a long viaduct and the 17/18 car ice trains passing along at speed into the distance!.
the trains must cover a tremendous "mileage" every day simply because of the size of the layout and mileage of track available!. wonder how long the components last till they need replacement/service!.
its amazing and anyone who loves model railways shud try to make the pilgrammage there at least once!.
