DCC Circuit Breakers

IMG_0894

The DCC circuit breakers (PowerShield X’s)on the main HO Gunyidi layout have now had the optional short‐circuit buzzers fitted (the round black things in the photo above), so they now make a noise when there is a problem. If you are operating on the HO layout and your train stops — listen out for the buzzer. If you hear it you have a short circuit and lost power — if you don’t hear it, it is probably just dirty wheels and/or track!

The next step will be to install LED indicators up on the end wall so you can tell at a glance which finger of the layout it is that has the problem.
