Six hours of track, three tunnels and not a single word of narration.
The film opens on a frosted windscreen and the sound of a diesel engine idling in the yard at Ardle. Nothing else happens for nearly two minutes. Then a signal changes from red to green, the brakes release with a sigh, and a 1,200-tonne aggregate train begins to roll towards the hills. Six hours later, the same camera is still running.
The Mountain Freight Line is the latest work from Calder filmmaker Odile Harcourt, and it is a deliberately unfashionable thing: a single, uninterrupted cab-view recording of a freight run from the valley floor to the quarry sidings beyond Harrow Moor and back again. There is no music, no narration and no on-screen text beyond a title card. The film premieres on Friday night at the Ardle Picture House before going online, and it has already sold out its first two screenings.
What you actually see
The route climbs 430 metres over 38 miles of track, much of it single-line with passing loops. Viewers pass through three tunnels – the short Kell cutting, the curving Brackenside bore and the long, dripping Moor Tunnel, where the screen goes almost completely black for four minutes and the only light is a faint smear of the headlamp on wet brick. Harcourt refused to brighten it in the edit.
In between are long stretches of sheep pasture, dry-stone walls, a level crossing where a farmer in a quad bike lifts a hand, and the reservoir at Coldwater, which on the morning of filming lay under a sheet of mist so still that the train’s reflection appears briefly on its surface. The return leg, filmed in late afternoon light, runs downhill with the empty wagons rattling behind.
There are moments of drama, though they are the drama of a working railway. The train waits eleven minutes in a loop for a passenger service to pass. A deer crosses the line ahead and the horn sounds. Near the summit, the wheels slip briefly on wet leaves and the engine note drops; you can hear the driver applying sand.
Made with the drivers, not about them
Harcourt spent most of last winter riding in the cab with crews from the freight depot at Ardle before she was allowed to fix a camera to the windscreen. The drivers are never seen, though their presence is felt in the occasional click of a switch or the radio crackle of the signaller.
“I wanted people to experience what the drivers experience, which is mostly patience,” Harcourt said. “If I put a voice over it, I would be telling the audience what to think about the landscape. The track already tells you everything. You learn the rhythm of it, the way you learn a piece of music.”
One of the drivers who worked the line during filming, Desmond Pryce, has been running trains to the quarry for nineteen years. He watched the finished cut at a private screening for depot staff last month and admitted he had expected to be bored. “I fell asleep in the second hour, I won’t lie,” he said. “But when I woke up I knew exactly where we were from the sound of the rail joints. That got me.”
A slow film for a fast audience
The film belongs to a tradition of so-called slow television that has found unexpected audiences in recent years, and its distributors are betting on the same appeal: viewers dipping in and out, leaving it on in the background, returning to favourite stretches. The online release will include chapter markers for each tunnel and loop, so that viewers can jump to the Moor Tunnel without sitting through the climb.
Not everyone is persuaded. A critic at a preview screening walked out after forty minutes, declaring it “a screensaver with a budget”. Harcourt seems untroubled. The Picture House has scheduled the Friday screening with an interval and a bar that stays open throughout, and audiences are being told they may come and go as they please.
The line itself may not run in this form for long. The quarry operator has said that output will be reduced from 2028, and the regional transport board is consulting on whether the route could carry a summer passenger service. If it closes to freight, Harcourt’s six hours may become an archive rather than an experience. Either way, the final shot – the locomotive easing back into the yard at Ardle as the lights come on – lands with a weight that nothing in the preceding hours quite prepares you for.
