The tracks are made from 15mm sq. rods. I drilled 8,5mm holes down from the top and had them countersunk to accommodate flathead screws. A standard plug for a 6mm screw is 8mm in diameter, so I could use the pre-drilled holes as a guide for the hammer-drill. The rails were fixed with a jig so that the holes could be brought down precisely. Then I pushed the plugs through the rails into the concrete and fastened the screws. Very fast method and the trackwork is rather sturdy. In bends you have to drill every 12" to 16", at least in the outer rail in order to avoid widening of the gauge resulting from the lateral forces a loco is exerting when going round.
