You need to change the options within the booster and tell it not to forward the short to the command station. You can change the actions in the track power options.

I would also feed the turnouts directly from the YD7001 as an accessory bus and would not feed any track from the YD7001, only feeding track from a YD7403 which would ensure you can always operate the accessories, even when there is a short of the track.

Thanks for responding Iain,
Did you mean the Button Action menu? It defaults to "Power On/Off Global", so could you mean "Power On/Off Local"? (I can't test that for a few days unfortunately)
The only other option that looks promising is the Track Output menu where it has some Short Circuit options but none look specific to a global reaction to a short.

I take your point on the turnout control YD8116s being fed from the Track Output of the YD7001 as an accessory bus. I did consider that and will probably do it now. Thanks.? In that case would you still have separate power supplies for each YD8116 or loop the power input pins to the signal input as is shown in the quick start guide? It would save a little money and let the YD8116 rectify some of the track power to power the module.
