Compagne desgravillons et du sable de la Brettone (Breton Sand and Gravel )
The layout in its entirety, photographed in my back garden. Hence the rather intrusive fencing.

This view does however show the other building, namely the engine shed. This is made from a wood frame, with infills of thick 'cornflake packet' cardboard to provide the slats. Outside the engine shed may be seen the other light on the layout, namely an item of common street furniture.
