Walk the Brampton Valley Way between Market Harborough and Northampton and the ground tells on itself. The path is flat in a way ordinary paths aren't, held above the fields on an earth shelf too deliberate to be geology. At a certain point the brick edges of a platform surface through the nettles, with numbers cut into the stone that nobody has a reason to read. This was Lamport. A station on the Midland line from Northampton to Market Harborough, which carried passengers until 1960, and then stopped carrying them, and then stopped being a line at all once the freight traffic fell away two decades after that.

Lamport closed early, three years before the report that came to stand for the whole thing. The Beeching cuts were the formalisation of a closure programme that had been grinding away through the 1950s, a momentum the 1963 report only accelerated. The Reshaping of British Railways in 1963 and The Development of the Major Railway Trunk Routes in 1965 proposed that roughly a third of the British railway network be closed. Over two thousand stations and around five thousand route miles. The figures are rehearsed so often they feel like a creed; what matters more, walking the ex-lines, is that the geometry never leaves. British Rail sold bridges for scrap and embankments for development, but plenty of the corridors survived because nobody quite got round to them. They became nature reserves by default. They became cycle paths when councils went looking for free linear infrastructure. The Trans Pennine Trail is a Frankenstein of them.

What strikes me about a trackbed is how much effort was put into hiding it from the natural gradient of the land. Cuttings through shale. Embankments raised over streams. Bridges at exactly the height a fireman needed. You can't walk these corridors without noticing you're travelling on engineering that outlasted its purpose by a factor of three or four. The steam age poured this much reinforced earthwork into a country that then changed its mind about it within a generation, and the country couldn't afford to remove the evidence.

Bobby Seal, writing about the Mold to Denbigh Junction line which closed in 1962, called it a phantom limb of twisted metal, grasping roots and overhanging trees. I like the phrase because it identifies what these walks actually feel like. There's the literal overgrowth, the hazel and birch coming up through ballast that hasn't seen a sleeper since the Wilson government. And there is the other thing. The sense that the corridor is still signalling, that if you stand at Star Crossing or Nannerch long enough you can almost hear the excursion trains coming through in a cloud of steam toward Rhyl, which they did, every August Bank Holiday, for decades, and then one year didn't.

I don't think hauntology is the right word for every old thing. It gets used promiscuously now, which drains it. But the Beeching routes are specifically hauntological in the Mark Fisher sense, not because they are spooky, but because they are the trace of a future that was paid for in reinforced clay and then abandoned mid-sentence. The embankments aren't mourning anything. They are just there, still raised, still flat, still arrow-straight across three parishes, waiting to be told what they're for now.

The Borders Railway reopened thirty miles of the old Waverley line in 2015, the longest new domestic railway built in Britain in more than a century. The trackbed was largely intact, which is the only reason it was possible. Elsewhere the bridges had already gone, the cuttings been infilled, the route chopped up by A-roads and warehouse estates. The choice to reopen a line is usually a choice to admit that the original decision was wrong; the ability to reopen depends entirely on how completely the original decision was enforced.

Half-erased, half-preserved. That's the settlement the cuts left behind. Not a ruin. A suspension.
