Highland Main Line


The Highland Main Line is a railway line in Scotland. It is long and runs through the Scottish Highlands linking a series of small towns and villages with Perth at one end and Inverness at the other. Today, services between Inverness and Edinburgh, Glasgow and London use the line. At Inverness the line connects with the Far North Line, the Aberdeen-Inverness Line and services on the Kyle of Lochalsh Line. All trains are diesel-powered.
Much of the Highland Main Line is single track, and trains coming in opposite directions are often timed to arrive at stations at the same time, where crossing loops permit them to pass. Journey times between Inverness and Edinburgh or Glasgow are approximately three and a half hours.

History

The vast majority of the line was built and operated by the Highland Railway with a small section of the line between Perth and Stanley built by the Scottish Midland Junction Railway, amalgamated with the Aberdeen Railway to become the Scottish North Eastern Railway in 1856, and then absorbed by the Caledonian Railway in 1866. Originally, the line between Inverness and Perth went via Forres, but the Inverness and Aviemore Direct Railway was opened in 1898 to allow for a more direct routeing.
There are two significant summits on the line; Drumochter Summit between Blair Atholl and Dalwhinnie, and Slochd Summit between Carrbridge and Inverness. Other distinct features on the route include the viaducts at Culloden and Tomatin, the spectacular mountain pass at Drumochter and the severe gradients encountered in both directions, particularly the extended climb from Inverness to the Slochd summit which averages around 1 in 60 the whole way.
In the 1960s, many sections of the line were converted from double track to single track. In 1976, 23 miles from Blair Athol to Dalwhinie was redoubled. In March 2019 Network Rail completed a program of works to increase capacity on the line and support the introduction of InterCity 125 sets on ScotRail services with passing loops and platforms extended.

Stations and services

As of 2020, there are stations on the line as follows:
Services on the line are provided by Abellio ScotRail and London North Eastern Railway. A roughly two-hourly Abellio ScotRail service operates between Perth and Inverness throughout the day with 11 trains in total in each direction, with all services running from either or . The London North Eastern Railway service is titled the Highland Chieftain, which departs Inverness at 08:00 and runs to London King's Cross via the East Coast Main Line, arriving in London at 16:00. The return working leaves London at 12:00 and reaches Inverness at 20:00.
The Caledonian Sleeper travels overnight between Inverness and London Euston via the West Coast Main Line. This joins portions from Aberdeen and Fort William at Edinburgh Waverley and south of there forms the longest locomotive-hauled passenger train in the United Kingdom with 16 coaches.
All trains between Perth and Inverness call at Pitlochry, Kingussie and Aviemore. Most ScotRail services call at Dunkeld & Birnam and at Blair Atholl, with the stations at Dalwhinnie, Newtonmore and Carrbridge being served less often. On Sundays, a couple of services continue through to Elgin, calling at Nairn and Forres.
