Now chicken wire is ok, but can be very prickley to use, so towards the rear the ply formers are first overlaid with a lattice mesh of strips cut from a cereal packet (Curiously Cinnamon - for the record!). Again newspaper and white PVA is painted on; in layers. The buildings are sat on a plywood piece that will be removeable to afford access to the servo unit below. These are not the final buildings, but are used to give an impression of scale etc.
I now need to go cut some more formers and buy some more cereal, if I were modelling a later era perhaps 'CO-CO pops' would be the preference, but as it's steam era 'Puffed Wheat' will be adequate.
