A slight novelty layout was Brooklands (O), modelling construction of the banked motor racing track.  Really, just an O gauge shunting layout and none the worse for that.

I like Woodbury Wharf (OO9).  A very simple one-piece cameo layout, but a good place to watch the trains go by, interesting scenery and a lovely backscene.  No joins on a small layout!

Tidworth NSE (OO).  Modern image as it was 30 years ago?

Chitterne, a GWR branch in EM.

Sturminster Newton (N).

A quiet moment on Brucklees (OON3).  But the Irish narrow gauge was often very quiet!

Swiss mountains (and a busy station) on Griswald (N).

And finally, Brian’s Trains (N and continental.)
