More rail track between Inverness and Beauly

It's around 8am on a dusky day in July 2016, and I'm standing on the far platform of Tain railway station, gazing out into the misty depths of the Dornoch Firth. The previous night I had come up on the late train - the 21:06 - from Inverness, though there's also a midnight service north. That left from Platform 7, which, intriguingly enough I had to walk across a car park to reach. Very few rail journeys start with a walk through a car park.

But, increasingly often, many, many journeys from Wick and Thurso to Inverness involve a walk across a car park. This walk culminates with getting into a car and, well, driving down the A9.

And why is this? There is a perfectly good rail line linking Thurso and Wick with Inverness, via the commuter towns of Dingwall, Tain and Invergordon, with four trains up it and down it each day (only one on Sundays). Many people marvel at the beauty of the line - it traverses all kind of landscape; the Beauly Firth, the Dornoch Firth, the Cromarty Firth, the mountains of Sutherland, Loch Fleet, incredible seascapes, marshy vistas, and vast tracts of peat bogland (the Flow Country).

The line also connects with the NorthLink ferries north from Scrabster, near Thurso, to Orkney, and many people use these each year. In fact, I do. It's why I was at Tain in the first place.

At Dounreay, on the north coast near Thurso, there used to be a nuclear power station. As this is decommissioned, things are transported out to Sellafield by rail. There's also timber extraction going on near Kinbrace en route - and the trees could be transported by rail.

So why are people not using the line as much?

Unsurprisingly, it's to do with the service. Things have become very unreliable. Delays and cancellations occur very frequently. Stops are often omitted at some of the line's busiest stations - including Thurso and the recently-reopened Beauly and Conon Bridge - to make up the time lost. The chronic problems behind these occurrences are caused by a combination of missing infrastructure and absent crew members. Out of these two, the infrastructure is the biggest problem with the line. But why is this?

Well, the line is single track for its whole length, aside for some 'passing loops'. This is where there are two lines, or 'double track', but only for a short distance (think road 'passing places'); and there are loops at Muir of Ord, Dingwall, Invergordon, Tain, Ardgay, Lairg, Rogart, Brora, Helmsdale, and Forsinard. Otherwise, the train's can't pass each other. Because of this, delays can build up, causing a knock-on effect that leads to cancellations and skip-stopping.

The stretch of railway between Inverness and Dingwall has only one passing place, at Muir. But this line is shared with the service to Kyle of Lochalsh (for Skye) and sees 13/14 trains per day in each direction (7 on Sundays). That's nearly 30 trains a day; and the constraints provided by the lack of track on the Far North Line, in particular between Inverness and Muir, mean that many, many of these are delayed, or cancelled.

And so we return to Tain. My train northwards arrives a couple of minutes late. Not much of a delay, though we manage to pick up more and more delays on route, so that we end up around 15/20 minutes behind time on reaching Thurso.

This makes commuting between the towns and villages on the southern section of the line and Inverness very difficult. And it also severely affects the northern end, too; because Thurso serves the ferry services at Scrabster and Gills Bay to Orkney. People need to be able to make their connections; being shunted out into a taxi at Wick doesn't help with things.

But there is a solution.

Until 1966, there were six miles of double track between Clachnaharry - to the west of Inverness - and Clunes, near Kirkhill.

Since this was ripped away, this bottleneck has become worse, and worse, and worse.

This is the solution; the Lentran Long Loop, as it's become known to the Friends of the Far North Line (or FoFNL). But why the name?

Well firstly, it would go through the Lentran are. And secondIy: in railway terms, a 'dynamic loop' is a passing loop that's long enough to allow two trains to pass without stopping. For example, there's a couple on the main line south of Inverness, and there's one on the line from Glasgow to Barrhead and Kilmarnock.

Having the Lentran Long Loop would improve services massively. An hourly service from Inverness to the towns of Easter Ross - Beauly, Muir of Ord, Conon Bridge, Dingwall, Alness, Invergordon and Tain - would become possible. Scenic tourist trains could run down the line, boosting the local economy in a ways similar to the North Coast 500 road route. The line could become a major freight corridor.

But, more importantly than all of those: the trains could run on time.

The ball is in your court.
