‘Overdale Tunnel’ – let there be dark…
Added a coat of black paint to the inside of 'Overdale Tunnel' today. I wanted to do this while it is still possible to reach without damaging any of the work already done.

The portal at the 'Dalesmouth viaduct end of the tunnel got a coat of paint first. I've painted everything, including the track, which will need cleaning when it's dry.

The portal at the 'Overdale Quarry' end of tunnel with its coat of paint. I have also started adding some more contours to the hill in the back corner.

In this view you can see both ends of the tunnel and more construction work at the back corner. These contours begin to define the notch through the hillside made by the stream, which ends with the waterfall in the foreground.
I have used some of the irregular offcuts of cardboard at the top leading edge of the hill to define the shape. It will also give a starting point for pasting the landscape covering to.
