I always wished they would expand the train layout further back. There is an arboretum near me that has a huge G garden railway with a relaxing park & water feature. Having something like that would be perfect for those dreadfully hot days, to be able to grab a beer, find some shade, and watch the trains. This attraction in Germany is small, but popular. In fact, if interest has lessened over the years, it's only because the layout itself had lessened. I think a larger layout with some impressive rock work as it winds around a relaxation park would be a wondrous addition. A simple horse shoe shape with seating in the middle and small fountain fed by a waterway in the layout itself. Not too elaborate, but attractive and relaxing. I'd spend even more money in Germany so I could hang out there longer!
