Trying to sell our house at the moment so I decided to build a diorama just to get some practice. I picked up a piece of steel flexi track for a £1. As it is only going to be a display and program track steel rail isn't a problem. Anyway I found a piece of scrap furniture board and attach a bit of 40mm square softwood for the trackbed. I have laminated some polystyrene with PVA. When it's dry I intend to shape the styrene to leave the track elevated with an embankment down to a field.
