QUOTE (Mike H. @ 2 Dec 2008, 21:55) <{POST_SNAPBACK}>Wondering how other people have done this. My layout contains a fairly long section of elevated track. To carry it I basically bodged a 'system' using thin ply for the trackbed, topped with cork tile, battened underneath by a strip of 1" x 1/4" timber, the whole thing built in strips and glued/nailed together. Then the trackbed held aloft by pairs of timber struts. I've found that this 'works' insofar as I have managed to create a fairly sound trackbed with gentle gradients and plenty of flexibility. What have other people done?

This is how I've done it:

You can also see the final result in the YouTube videos here:

Note that the gradient of all slopes is a prototypical 1 in 1 and a half. Steeper than this and real soil-based slopes will slip.
