Actually on Combwich I'm tempted to simply using push pull rods for the points and dumping the control panel. Bonus being that much of the cross-layout wiring could be dumped - less to go wrong and easily fixed - above all CHEAP!!
I have Mendip Colliery to get on with, that's all being properly done with C&L and now a lot more scratchbuilding. The quickie would just use ready to plant stuff, Tillig track and a dose of creativity.
