Reroject for a Rainy Day - A G Scale Diorama
Well this is what I've decided to do in the end.
Although I liked the idea of Tony's tunnel mouths, I then thought maybe a 3 arched viaduct, with tracks coming from under two of the arches would look good.
So I then drew this up on a large scrap of 3mm plasticard, but drawing curves, plus the thought of then having to cut the tunnels accurately from this thick material (I don't have a bandsaw) led me to thinking it would have to be an all straight line cut job (score and snap).
So I roughed up this design in MS Paint and I seem to have gone back to the idea of the riveted steel plate bridge as before, but a longer version, supported on brick pillars to give 3 'voids' (can't really be called arches) underneath. Tracks thus run through 2 of the voids, with the other being 'abandoned' (and possibly bricked up).
To 'tie in' the bridge to the low tree line on the backscene, the brick work will be 'dropped' to try to give the effect of the bridge deck changing to a slope....
