So while I am not physically doing track changes, I have to so me re-work of the electrics for the turnout motors - ah well , keeps the grey cells active !

Devan & Bruton Jns are already interlocked.

Brian, signals are set by the main signalman (me) to green if the approaching turnouts are set correctly & revert to red when the loco passes the signal.Less drastic changes there Ron especially if the interlocking solves the problem are your signals linked to the turnouts?

if a loco travels from one end to the other via the goods yard, it navigates 18 turnouts.

I read elsewhere that you'll have to re-do all your timetables - is that still the case ?

You could argue the complexity keeps your brain active Sol ……………………… :hmm I hope it does !

part of the overload/ short circuit protection - globes in series with a toggle switch to be able to isolate subsections.
Across the globes 18w & 5W, is a full wave bridge rectifier that powers a buzzer so under a short circuit, voltage drop across the globes is enough to activate the buzzer but when the globes are cold, no voltage drop so no buzz.

That short circuit setup is neat, I could use something like that!
Can you share the wiring and components setup with enough clarity for an electronics dummy (i.e. me)?

and the bigger one under the layout

My writing is Cr*p , the buzzer code is AB3452

Saw that on the Watchit thread and thought it must be something to do with short circuit protection (guessed it wasn't an indicator when trains go round cornersand for those who maybe interested in what this is on a DCC layout

Hi Sol,
Disappointment I'm afraid. I followed your plan with the sole exception of omitting the 5W lamp and I just finished testing.
When I create a short the 18W lamp produced the very faintest red glow before the NCE Power Cab detects the short and resets. There wasn't enough voltage drop to trigger the buzzer.
My NCE is only over a year old, perhaps their internal short protection in more sensitive to changes in current or whatever it monitors now?
Any other ideas?
Colin
