Druimuachdar Pass Summit is 1,484 ft above sea level. The line is double track. It is the highest main line summit in Britain. (The highest standard gauge line was at Wanlockhead at 1,498 ft, closed 1939.)
The line was doubled in the late 1890s, completed around 1900. A double track extended from Blair Atholl to Dalwhinnie.
The Highland Railway was keen to double this portion of the Highland Main Line as it was arduous with trains requiring piloting. Obviously slow moving trains in a single track section greatly reduced capacity. Both the Forres [2nd] original route and later Carrbridge route to Inverness fed the line south.
It was reduced to a single line in 1966. It was redoubled in 1978.
Also known as County March Summit. Nearby, during doubling of the line, was County March Signal Box [Highland Main Line].

Pigs and boars
A number of locations on the Highland Main Line refer to pigs and boars.
West of Druimuachdar Summit are two striking hills, An Torc (the Boar of Badenoch) and, to its south, Meall an Dobharchain (the Sow of Atholl). The profiles resemble hogbacks.
Slochd Viaduct crosses Slochd Mhuic - pig's den in English.
