I had an idea today, from looking at pictures of construction of the reinstated Nuneaton flyover...
Is there any reason why expanded polystyrene should not be used as the roadbed on a model railway, providing that beneath said polystyrene there is a firm foundation? It would be a hell of a lot easier for my purposes than building the L girders which would otherwise be required. I'm not thinking of using it extensively, as it would be awkard putting droppers in to the track bus (I use DCC) and burying point motors, but for a long plain track curve halfway up a hill it is much easier than cutting wood to shape- plus I'm using the polystyrene as the basic firmament for the landscaping.
