Yes, unfortunately the wye formation requires polarity switching or an automatic reversing unit just like in your previous "fun" with reverse loops!I'm DCC what about wiring please will it involve DPDT switches?

No experience of this particular one, it says maximum 6 amp continuous and says it can work up to G scale. I think to be on the safe side assume 3 small LGB locos running at the same time in the switched section (the station in your case) with their smoke going.Would the Digitrax AR1 work for me please?

Sarah,
how about something like this?
View attachment 241582
Your diagram above has 7 turnouts, this one has 5.
You dont technically need a wye switch to make it work..

Probably be ok but my issue would be what will you do to protect it from the weather?Would the Digitrax AR1 work for me please?

Looks like it will do the job.Would the Digitrax AR1 work for me please?

I put mine inside buildings too, up high near the roof space.I've put autoreversers into small buildings right near the gaps, which minimizes wire length, a small lineside shanty mostly sealed, with a way to vent moisture.
You can also try a waterproof box, but because the current limit adjuster may have to be accessed, not always convenient, and nothing is really waterproof. I have found it better to be in an enclosure that can purge moisture buildup and not take in a lot of moisture than fight the laws of physics of expansion/contraction/pressure

In spite of all the suggestions I would think that Sarah would be better off mounting it in a small box in her Shed with wires extended to where they need to be which as far as I can remember will be pretty close. Better to be safe than sorry. I also think that most of the suggestions are comming from users of LGB or Massoth revercing units which sit in a small weather resistant (note not proof) box.I put mine inside buildings too, up high near the roof space.
I also put the buildings on 'feet' (dome headed screws) so that air can flow underneath and moisture can escape....
Sound advice.I don't think Sarah will be, but to all...
DON'T leave power on for days and days... Although the slight heating of powered electronics will keep things (slightly) drier.. Or normally damp climate does not sit well with constantly powered low current electronics..
If you get condensation, there can be a migration of the copper tracks, due to electrolytic action.
I electrocuted real frogs when I left my power on overnight once....At first I left the DCC power on 24/7... two things happened.... I found electrocuted frogs (real frogs) spanning the rails....
