RCHS Annual Clinker Memorial Lecture.
The 2026 lecture “Legacy Railway Structures: Assets or Liabilities” was delivered by Graeme Bickerdike at the Met Hotel, Leeds on Saturday 30th May 2026.
The retrenchment of Britain’s railway network in the 1950s and 1960s left a lasting physical legacy in the form of thousands of disused structures scattered across the landscape. Most have heritage value as a reminder of our pioneering past, some have been reclaimed by nature to form wildlife corridors and many have the potential to be incorporated into future sustainable transport routes. For example, the National Cycle Network uses hundreds of miles of dismantled railways and their structures, but some bridges and tunnels still find themselves under threat. Do asset management regimes fully recognise the opportunities they present?
National Highways became the unlikely custodian of the Department for Transport’s Historical Railways Estate but, in recent years, has made a number of controversial decisions (some might say blunders), even driving through some demolitions without public scrutiny under misapplied emergency permitted development rights.
In his lecture, Graeme Bickerdike examines how National Highways got it so wrong, and looks at what has changed to hopefully prevent a recurrence. For 20 years, he has researched the history and recorded what is left of several hundred viaducts and tunnels on closed lines, from northern Scotland to Cornwall and Kent. This interest manifests itself online in the form of his Forgotten Relics website and a book called “Railway Wonders” which charts 100 of the UK’s most noteworthy disused structures. He is also a regular contributor to “Rail Engineer” magazine.
Graeme provides support to a community group seeking to repurpose the 1.4-mile long Queensbury Tunnel in West Yorkshire as part of what Sustrans has described as “an iconic and nationally significant” active travel network connecting Halifax with Bradford and Keighley, and is also a leading member of the campaign to resist National Highways’ attempts to infill or demolish dozens of legacy bridges, many of which have the potential to fulfil useful future transport roles.
