We don’t stock the EM equivalent of a tracksetta for the ready to lay track. It is an interesting thought though. The company that makes the ply sleepers for us would certainly laser cut them for us. When we are back to some sort of normality I can quickly see what sort of cost they might be. That might encourage some sort of demand
I’m not sure whether you could use an OO gauge one. As far as I can tell (I’ve never used one) they are deigned to sit above the sleepers a fit snugly inside the rail
Timber Tracks do the equivalent of what you are suggesting.
A very comprehensive set of curves.
