Smallbrook Junction IOW

I have started to look at the feasibility of first designing and perhaps building this Junction. I have done the easy bit but yet to find out if this is what is wanted

My next objective is to try and find, read and understand how to make breaks in the rails then overlay partial templates

I am thinking my real option though is to paste partial templates on top, certainly quicker and less frustrating.

One other area is check rails, I am not too certain about how long the common crossing wing rails should be

Please don't spend too much time on the plan as I am not certain the basics are correct
