Disused tunnels database

Disused tunnels database

Research to expand our database of disused tunnels continues to pay dividends. Many thanks to those of you who have sent in contributions. If you can help with any details, omissions or corrections, please click the ‘contact us’ link in the sidebar to get in touch.

By clicking on the relevant column header, the database can be sorted by name, yardage, company or opening/closure dates. Hover over the abbreviated company name to see the full version. New tunnels are highlighted by a red tip; modified entries are in orange. More information or pictures – where available – is provided via the Link button.

Tunnels which were opened out either during or after the railway’s period of operation are excluded. Only those that still exist – even if now buried – are listed.


  • (g) length determined using historical maps and Google Earth’s measuring tool
  • ~ scaled length/approximate year
  • ? evidence uncertain
  • < earlier than/less than
  • > later than/more than

Click here to search the database by map. Each tunnel is marked at the midpoint of a straight line drawn between its portals (which can prove deceptive if the tunnel is curved). No buried tunnels are shown.

Most of the tunnels on the database can be viewed in GoogleEarth by opening a .kml file developed by Antony Badsey-Ellis. Download the ZIP to your hard disk by clicking here, then extract the .kml and open it using GoogleEarth.
