The Aigle–Leysin railway line is a narrow-gauge railway line in the Chablais area of southwest Switzerland. The line was opened on 5 May 1900, a -gauge cog-wheel railway using the Abt rack system. It was the first such line in the region. The line was built by the Chemin de fer Aigle–Leysin.
Nowadays it is joined in Aigle's main railway station by express trains of the Swiss Federal Railways together with those of three other, local, narrow-gauge railways: the Aigle-Ollon-Monthey-Champéry Railway (AOMC), the Aigle–Leysin Railway and the Aigle-Sépey-Diablerets Railway (ASD).
The Aigle–Leysin railway line is 6.52NaN2 long and rises 1047abbr=onNaNabbr=on from its terminus outside the main line station in Aigle to its summit at the Grand Hôtel at Leysin. The first 1 km of the route is through the streets of Aigle from the railway station to the railway depot where the train reverses to enable the powered vehicle to be at the rear of the train for the uphill journey, normal working on a rack (cog-wheel) railway. From this point the line climbs steeply through the vineyards, the steepest gradient being 1 in 4.3 (23%).
The operating voltage of the line has changed four times, increasing from 600 V DC at opening, first to 650 V DC, then in 1946 to 1300 V DC, and later to the present operating voltage of 1500 V DC.
In 1975 the four local railway companies, Aigle–Leysin, Aigle–Ollon–Monthey–Champéry, Aigle–Sépey–Diablerets and Bex–Villars–Bretaye (BVB) merged to form a single operating company, known as the Transports Publics du Chablais (TPC). This brought about increased co-operation between the companies in the provision of community-based services.[4]
In 1985, the Federal Government informed the Aigle–Leysin Railway, and other privately operated railways, that it would cease all funding the following year, however they renewed a federal concession for a further period of 50 years. An agreement was signed between the Canton of Vaud, the communities served by the railway and the Aigle–Leysin Railway and its partners to renew rolling stock and upgrade the track.
In the mid-1990s, faced with greatly increased operating costs, the Canton of Vaud and the communities served by the railway petitioned the Federal Government to revoke its 1985 decision. The Federal Government did so and in 1996, recognizing the importance of this regional line as a public transportation carrier, awarded the line with a contract to provide a public transportation service. This brought about, in 1999, talks which resulted in the founding, the following year, of Transports Publics du Chablais as the parent body of local public transportation with the four local railway companies as founding members. The railway now operates as line A under the TPC banner.
, Transports Publics du Chablais rostered two locomotives, one kleinlokomotive (French: tracteur), six railcars (French: automotrices), five driving trailers, two goods wagons, and six utility vehicles for service on the Aigle–Leysin line.[5]
