It did exist as a Trainz route, payware, but now sadly unavailable.
User 2995Valliant bought the copyrights to this route and is in the process of enhancing it but since the advent of T:ANE I think he's having problems with the project.
I have a copy of the original payware version and it installs in to T:ANE with very few problems but it looks quite dated.
I do remember that someone was in the process of creating this route, quite a long time ago, I don't remember his user name though and he's not been seen on the forums for a long time.
Not a lot of help for you, you may have to create your own version if you want the route.
