This level hopes for you to try to make every single tile useful. This attitude kept me stumped for about a week, which is longer than any other level on the workshop. If you're hoping to clear this level, it's my sincere advice to forget about making the railway satisfying and just connect all the stations by any means necessary. Until someone proves me wrong (preferably with visual proof), I have to warn all players that this island has no satisfying solution. I would know, I've been pulling my hair out to find one - to no avail.
