Thanks again for the replies :))) Really the purpose of this was to see if I could, more than to improve a factory. It was my first experiment using more complex circuit logic so I was more interested in the logic side of things than the efficiency :lol: Maybe on my next world I'll add more circuit ...

Thanks for the replies :)) Tertius you are 100% correct in that implementation, there's no memory cell because I'm not advanced enough to know how to make them yet (kinda wanna work it out tho). So yeah, we only have one tick of signals per station so it does end up kinda slow. Bit masks sounds like...

For context: I have a series of train stations, reading train IDs into unique signals (unique per station). This is then fed into a 1hz clock which compares the incoming signals with a list of 30 known signals, then outputs a single "clock" signal matching that train ID. So essentially: --...
