They say when laying model railway track, to stay away from double slips, (mainly because they are difficult to wire up), but this also applies to curved turnouts. We look for ways to have maximum length in our yards, and to put in a curved point can save almost a foot (30cm) in space.
Curved points may have a place, but not in spacing saving, as we try yo obtain geometry that usually pushes them out of gauge.
A new number 6 straight, left hand was purchased and the yard result being a bit shorter. Yet to connect up the all the track, power and test.
