Looking for a v-e-r-y old route

When I first discovered train simulation and what has eventually become Train Simulator, I downloaded, drove, and even made scenarios for a route the name of which I cannot even recall. All that I can remember of its late history is that it was more or less taken over by Ottodad, who extended it beyond measure until it no longer functioned. Does this strike anyone as familiar? If so, please post what you know in this thread, especially if the route's installation files are still available. I'd love to revisit it.
