Roadbed colours

[Gunzel73]

This idea combines three features already available.

1) Show > Roadbed / Trace / Width
2) Track > Standard / Embankment / Tunnel / Bridge
3) 3D view > Color / Texture for Roadbed / Sleepers / Track / Ground / Underside / Tunnels

Could a feature be added to the in 2D view, to allow selection of different colours (or textures) for the trackbed width trace for each of the four track types, e.g. green background for embankments, grey for ballasted, white or transparent for bridges? Otherwise tunnels, standard and bridges are distinguishable, but I don't know how embankments are flagged?
