I can't answer for Märklin HO. I don't know how the "common rail" typical of Märklin HO installations affects operation.

I can answer for two rail systems. (Trix, LGB, etc.) I'm using a CS3 with two boosters to operate my mostly LGB two rail outdoor layout. Each booster region is isolated on both rails. I had a short occur at a turnout a couple of days ago. Only the booster for the region involved shutdown. The other booster continued to operate.

My experience is that only the booster shuts down.

The booster does inform the CS. But only the booster shuts down.

The CS2 used to offer two options with the message
- X = close the message box and leave the booster shut down
- Y = "I have fixed the booster short" , retry to power up


The CS3 only offers the
- (Cancel Window) = close the message box and leave the booster shut down


The niggle is that with an "X" , and after you have cleared the short, you generally do need press Stop, then Start to retry - thus annoyingly stopping the whole layout.

However the CS3 does have an "Control" event function, for use with an event , that allows for just the "GO" (without needing the STOP first)


You may therefore configure an event and reference it on the layout diagrams or via a button connected as the trigger for the event


P.S. While not being readily useable, you can check the Info for the booster and will see a fixed "0" when the booster has turned off.

If you have software monitoring the ether then this detail may be seen in the stream
