Inside Staple Hill Tunnel
Introduction
The photograph on this page of Inside Staple Hill Tunnel by Ken Walton as part of the Geograph project.
The Geograph project started in 2005 with the aim of publishing, organising and preserving representative images for every square kilometre of Great Britain, Ireland and the Isle of Man.
There are currently over 7.5m images from over 14,400 individuals and you can help contribute to the project by visiting https://www.geograph.org.uk

I seem to recall that the lights are not on all the time, only during daylight hours when cyclists are using the Bristol & Bath Railway Track.
