I don't know if anyone on the forum has ordered these boards or built any; but I am happy to advise that I have done a test build and they work exactly as intended. They are quite stable now with no unintended trips or resets. Also the yellow cancelling when another train enters the block works exactly as it should. All the files posted immediately above are current; I have added an updated set of User Notes that contains a couple of edits and an expanded description of operation.
