Trains originate from bay platforms at Aigle, adjacent to the Simplon line of Swiss Federal Railways.

After listening to the arguments, the federal authorities agreed and the original concession was withdrawn to be replaced by a new one for a line from Aigle to Monthey via Ollon.

Passenger rolling stock has been regularly updated since that time, with the latest delivery, two twin-car railcars (numbered 591 and 592), arriving in 2001.

Although the line to Morgins was not built, the present day system does include a short, one kilometre section from the town station in Champéry to Champéry-Planachaux, where a lift forms part of the public access to the mountains.

Nowadays the AOMC is part of a larger, regional system operated, along with local bus services, by the Transports Publics du Chablais.

These platforms feature new lighting and public address systems and have easy access from the town's Place de la Gare.
