Mine would be an oval of track nailed to an old flat door I believe. It had a point with a siding coming off it and some fencing made of nails with some cotton thread wound around it to look like wire. Ballast was made of sawdust mixed with grey paint (a bit gooey for real ballast) and the grassy areas were just green spray paint. Stock was a Hornby 0-4-0 with some four wheeled carriages and a few trucks including the ubiquitous 'Bolsover' open wagon and a tanker wagon. 1982. Hours of fun Anyone else?
