I see somebody with my same taste, great job especially on the Thalys one, I decided to do the much simpler one but your looks fantastic I love all of them. It's a shame only one of two coupled train spaws with the livery so I don't know how realistic a Thalys is coupled with a TVG is, but I still love it, it really adds to the variety of the route
