Aigle's main railway station is not only served by the trains of the Swiss Federal Railways but also those of three local, narrow-gauge railways: the Aigle-Ollon-Monthey-Champéry (AOMC), the Aigle-Leysin (AL) and the Aigle-Sépey-Diablerets (ASD).
The operating voltage of the line has changed four times, increasing from 600v. d.c. at opening, first to 650v. d.c., then in 1946 to 1300v. d.c., and later to the present operating voltage of 1500v. d.c.
In 1985, the Federal Government informed AL, 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 AL and its partners to renew rolling stock and upgrade the track.
In the mid 1990's, 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, the founding of Transports Publics du Chablais as the parent body of local public transportation with the four local railway companies as founding members.
