Frustratingly, I have tried everything to get the mod working. Ive got harmony installed, used the tiles mod to open up the map, even looked up youtube videos but for some reason, no matter how many train connections I try to put to various stations to bring in outside connections, it simply doesnt work. I was sure to connect it to the edge of the map. I have no clue what im doing wrong, as I was sure to also set the network tool to default too.

Any/all suggestions would be hugely helpful.
