Looking better Keith.
I've never been one to like the curvature to be compromised with the inclusion of a tangent through the Frog but it does have its prototype usage, the Europeans liked them on their Feldbahns.
At the local Park railway, someone of lesser standards grafted a right-hand switch into a curve instead of building a more correct Y-switch. It irked me considerably so I rebuilt it, first moving the Frog location to a better position, It was intended to rework the diverging line curve to the right to avoid that tangential exit but the Park people wouldn't allow the incursion. So it was what it is.
The tangent in foreground was realigned after this was taken, improving the "flow" into the Blades.
Flow is important
