Any map size 4250 or larger should have a single railway in the shape of a ring going around the entire island.
To set this up on your server, do the following:
- Stop your server.
- Click "Configuration Files"
- Click "Config Editor" or "Text Editor" next to server.cfg
- Find the variable "server world size" and change the value to 4250 or above.
- Find the variable "server level" and make sure it is set to Procedural Map.
- Startup your server.
- It will take a couple of minutes to generate the new map/world, but once it's done you'll have a randomly generated map with the railway going around the island.
