Shadow Line:~ Field Notes

This way to photography

Wolverhampton is not deficient in rewilded wastes. These abandoned remains of its industrial past are etched with the grey-greens and umbers of nature creeping back. Down a cobbled street we found one such scrap of land. Most pass by without knowing it’s there — the end of the road is just another dead end to be ignored.

Along one side of the street, the railway embankment rises in sheer blue brick, braided with wires at the summit. Blue bricks are the stamp of the industrial Midlands. The red clay here is rich in iron, and when baked at a high temperature the iron turns the bricks a blueish-black — a small kind of alchemy. They are not only darker, but harder, denser, and resistant to water.

Opposite, the wasteland is scuffed roughly with the golden hues of moss and new-growth trees, lurking behind a crosshatch of wire. It is winter, but winter in its last throes. At the far end of the street, the wire was cut, and with a low shrug we pushed inside.

Beneath our feet, a soft blanket of moss and lichen spread out unnaturally flat, hinting at the layers beneath. An abandoned industrial building slept on the horizon, its colours blurred with the winter buddleia, weathered green upon weathered green, but angular against the tangled branches. Further in, through the tangle of undergrowth, a path had been cut by other explorers, human and animal alike, tracing a line through stiff grass, leading us gently downhill — the shape of former order now given over to quiet drift. The ground whispered of its past.

Following the path, we ambled down to where a large basin of open water had stolen trees, grasses, railings — all now half-submerged. Debris drifted across the dark surface: bottles accumulating into fragile rafts, and pale plastic forms — the ghosts of something once useful. The black water slipped deep beneath two arches of the railway line, as though it emerged from some hidden place within. Here, entropy had been set loose, softening edges and silting over purpose. Even the sign, once declaring the dangers of entering the tunnels, now hung half-submerged against a gaping, open gate, obsolete. All was quiet, still, uncanny — as if all this, including ourselves, might remain forgotten at this sunken threshold.

After we left, I scoured old maps. The darkness beneath the arches held a deeper secret — a literal one. These had once been tunnels for the Wolverhampton section of the low-level railway, owned by Great Western. Trains would rumble into the shadows here and re-emerge in the overworld some 350 metres southeast, at Lower Horseley Fields, before continuing on to Birmingham’s Moor Street and Snow Hill, and finally to London Paddington. The mossy flats that we’d crossed at the threshold were the remnants of the old railway routes. Where the tracks had once lain, nature had now placed its patient claim.

I later returned alone. I wondered how far the water stretched along the tunnels, so I followed their route overground to Horseley Fields. Familiar blue brick gleamed faintly in the distance and showed the way to the railway embankments. Within the crevice formed by their slopes, another pool waited, stretching away from the street and darkening into blackness beneath another two arches.

The whole route of the underground tunnels must be flooded, forming a canal — a shadow line beneath the city. Silent, still, dark water, stalking the daylight. An accidental canal, lost between worlds. Above it, the world carries on: streets end abruptly, fences quietly yield, and hardy blue bricks glint in the weak sun unnoticed.
