This series of pictures through Standedge Tunnel begins at the Diggle end.

The convoy enters the tunnel.

The first section of the tunnel is a brick arch built on stone walls.

Metal girders support the roof where the railway crosses over the tunnel.

The tunnel profile changes.

Bare rock faced section, with rock bolts visible.

A section where loose rock has been re-inforced with steel mesh and sprayed with concrete.

Jack arches support the roof above rock face walls.

Around half-way through, the tunnel swings to the right...

...and then to the left.

Low wide arches span one of the three wider passing points.

The light at the end of the tunnel becomes visible an hour before the end is reached.

Just inside the Marsden portal, wide arches overhead show where the railway crosses back over.

Daylight at Tunnel End, Marsden.
