The horn sounds great for me. It clips if you hold it down but short blasts are perfect.
Nice job.
As far as the route, when I get the tracks straightened out and look up some of the elevations I can upload what I have so far which is pretty much the Magic Kingdom and Epcot loops. I've used the stock stations for all stops except for the Contemporary and Epcot. I haven't even begun to look at what it would take to create objects and I don't want to reinvent the wheel if someone already has. Some of my turns are sharper than the real thing and the double track acting like a bridge isn't helping anything at all since you can't use the straighten tool (I have uneven turns in places that I'm trying to fix). I have the general shape correct but it's freelanced a bit here and there for the sake of simplicity. If you have objects that you can upload to the DLS please do. I will upload whatever I modify if anyone is interested.
