The tracks were painted: Vallejo German black-brown on the sleepers & some rust-colour on the rails. I then cut out two lengths of MDF, bevelled the edges and sprayed them dark brown. When dry, the surface was glued, the rails pressed down & a suitable railway ballast scattered over them.
The train & engine have been painted, washed in sepia, drybrushed in a dust-colour & then (the engine), in bright metal to show paint flaking.
Now that I know the tracks look good, I can work on another half-dozen.
