Circuit Diagram for LGB 5012N

[Gizzy]

I've been given an old LGB 5012N Controller to repair. It's the one built into a Signal Cabin.

I've taken the underside off to reveal the electronic circuit board or PCB. I can see it has become damp at some point.

But could anyone point me to a circuit diagram please?

I reckon I can repair it, but some prior knowledge would be helpful, thanks....

In a day or so, I could send you a photo from my controller.
