What points are you using, Rob? I'm guessing either the "medium" (12" radius) or Setrack (9" radius) Peco.
The layout I showed with the Rapido wagons on it uses the Setrack points, but not everything plays well on them as they're dead frog. I haven't been able to try a Sirdar on them yet...
I remember seeing Roy Link's original, ¼" scale Crowsnest in Railway Modeller when that issue came out, it must have been one of the first micro-layouts, though they weren't called that then. Aside from railway modelling, at the time I was also making up and adding detail to the Matchbox 1:76 AFV kits with their little diorama bases; Crowsnest to me seemed to combine the two varieties of modelling.
