It may be wired, but parts still don't work.
Some of the points in the yard aren't throwing- I think this will be a fault in the return circuit as it affects three points close together. In addition points 5 and 6 throw each other in one direction- that is just a bit of swapping needing to be done.
The biggset problem is that trains running Southbound stop at the first callon, but none of the buttons work. This is a fault affecting all so is either the supply to them or the return. If the latter a simple fix, but if it is the supply it has already been doubled up.
Its somewhere under this panel.......
