Can't Find Devon Co Entrance

[Concise Mallard 0]

So basically, I'm on the part of the game where you have to go into Devon Co from the railnet, but I solve the second railway puzzle to open the west gate. For some reason, the turnpads are green and I can't even interact with them to change the railways.

the solution for this puzzle is a lot simpler now, look for special WALLS ( still in the railnet )

I went through and rock smashed all of the broken walls but the gate won't open. Do I need to use a specific item on it?

go back to the railnet, near where you first found the train, you will find a new-ish area to explore.
