Its actually not that complicated, it will be a little tricky to build simply because of the short rail sections, the one section I am very conscious could trip me up is this where I need to try and be a bit clever where a running rail crosses across the knuckle of the wing rails, I am hoping plenty of check rails will keep wheels where I want them to go.
The other area where I doubt I'll get away with my original plan if the the 2 turnouts which have to accommodate a change in the side the narrow gauge runs, I was hoping to get away with only one switch per turnout, drawing c/3, but I think I'll need one switch for the right hand rail in the drawing and a second one for the transition of the narrow gauge to the opposite hand, if that makes sense.
Sequencing the build for this junction will also be critical, but as an old fashion properly trained professional track engineer I would hope I can develop a build sequence okay, not the most complicated layout I will have built but I think it will be the most complicated in anything smaller than 305mm : ft.
Straight board 915mm first though.
