Hello. I am in the US, and had to look up Barry turnout. This appears to be 2 regular TOs intertwined, like a double slip, but not.
In a recent post, I asked if anyone could provide a copy of a micro article from Model Rail Great British Model Railways. I understand that it is 3 box files, with the middle being a scenicked section with one TO. The two ends are supposed to be 3-track sector plates. You might consider following this using some arrangement with your Barry TO in middle.
Look at what I think is a Barry in the middle of this photo. In your proposed micro, the 2 track legs on one end could be on either side of the station platform. In the other direction, one track is your branch line coming in, and the other could be a tiny goods siding. If you have room for each end to be a little 3 track complete train turntable, you could have trains coming and going.
If it were me, I could not resist the urge to try and squeeze in a very small loco turntable and engine shed, if possible. I think this adds a lot of interest.
I admire your track building. For me to put together a Barry TO would be a struggle.
Regards, John Hutnick
