 I'm looking for any pointers to information about how to wire signals. I have a 'wish list' of functionality that might be too ambitious - so I'd also like any feedback about what sort of signaling is really most useful, and what can be ignored. The wish list: - Signals displayed trackside, at operator's control panel, and at dispatcher's control panel. - Signals green if block clear and turnouts aligned - Signals red if turnout misaligned or next block occupied (It would be nice if the signal indicated which condition was true - perhaps a yellow aspect if the next block is occupied? Does that complicate the wiring involved?) Does block detection provide information about direction of travel? It seems that if the next block is occupied by a train traveling the same direction, an approach/slow/proceed signal might be appropriate, but if occupied by an oncoming train, a stop indication is warranted. I'll be using Digitrax DCC, so I expect that I'll also use their block-detection circuitry, unless I hear about something else that looks like a better solution. I have no idea what I'll use for turnout detection - the current plan is to use mechanical levels to throw the turnouts, so sensing of position will need to be separate from actually throwing the turnout. Thanks for any info, Mike
