We have dugged out, filled the ducts with tile-sand and paved with tiles afterwards.
The tracks are made of 10 X 25 mm flat and the sleeper is 6 X 30 mm flat.
Track type is 7¼ inch = track 7, due to the small radius of the curves will be approx. 184 mm + 5 mm.
The length of the tracks is approx. 220 metres.
Hers is a drawing of the tracks in the garden.
