The next diorama I'm preparing is a small section of an embankment.
The base is again a piece of insulation foam approx 150mm square, shaped with a hot wire cutter and painted a brownish colour. The first photo shows the work done so far which includes a short length of Peco code 100 streamline glued into place and sprayed with Halfords grey primer. The code 100 track has been used simply because I happen to have lots of offcuts in a box and need to use them for something. The track was glued down with, yes you've guessed it, neat pva.
Painting the track and sleepers in a suitable dirty track colour will follow in a few days time as I have to take a trip up to Lincolnshire tomorrow.
