From 1st January 1946 the two companies amalgamated to form the AOMC and plans were put forward to bring the line up to date. Although not delivered until 1954, on the rolling stock side, this was mean the construction of four new railcars of Series BDeh4/4, numbered 511-4. Passenger carrying stock has been regularly updated since this time, the last delivery, two twin-car railcars (No's 591 and 592), arriving in 2001.
Although the line to Morgins was not built there was still one section of the present day system to be added, a short,just one kilometre in length section, from the town station in Champéry to Champéry-Planachaux, a lift which forms another part in the public access to the mountains.
Nowadays it is part of a larger, regional system operated, along with local bus services, by the Transports Publics du Chablais.
Important investment plans were developed by the AOMC in 1995 one of which involved the construction of a large maintenance workshop and stockholding facility. This work was completed and opened under the TPC, in 2001. The new dépôt at Châlex, alongside the line a short distance east of Aigle has over 26,500 sq.m. of space available for workshops and is the main stockholder for all three of the TPC narrow gauge lines. Space is also available on the site for expansion in the future should this be required. In 2006 the TPC commenced a programme of building works at Aigle in collaboration with the CFF/SBB/FFS. This was to bring together all three of the metre gauge lines at new platforms adjacent to those of the main line company. Work was completed in early 2007 when the services were brought together, the AOCM making use of the two platforms nearest the main line. These platforms feature new lighting and public address systems and have easy access from the town's Place de la Gare.
