Since joining the local model railway club (www.admrc.org.uk) a year or so ago, I’ve been helping out with their “Pentre Road” layout, which is based on the North-and-West route through Herefordshire. Latest thing to worry about has been exit stage right, for which I’ve found a nice road overbridge just south of the Dinmore tunnels. (see here; http://www.archive-images.co.uk/gallery/Archive-Colour-Images-of-the-Railways-of-Herefords/image/108/Dinmore_Tunnel_South_End_c1964 – though oddly flipped left-right).
Below is a quick mock-up made from a pair of scalescenes kits I already had; the brick bridge download (R011) for the main dimensions, and an ashlar retaining wall (R013) for the overlays; modified to give the steeply descending road and slightly skew bridge. I think the final one will be in plasticard, as I do think ashlar/rubble type structure need the 3d relief that textures don’t give. It’s not the neatest of builds, but will do for now and provide a reference to build the landforms up.
