Krustyland scenic railway?

I was playing around with my Krustyland and was wondering how it could look more like a real theme park. I was thinking about real life parks I have visited and what features they have, then I thought I would love to see Kustyland get its own scenic railway. Not just a single purchase item, but a whole construction where you can buy single items of track, carriages and even stations, maybe even crossings over footpaths etc. to construct into a whole. It would be an item that would grow as krustyland grows.
Don't know if any of the game designers read these posts, but if you do maybe it could be something to consider. Most of the big theme parks like Disney have a railway and I think my krustyland needs one too.
