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.
