[4] At its greatest extent, it ran from the boat landing stage on Lake Geneva in Clarens, via Chailly to Blonay, terminating alongside the station of the Chemins de fer electriques Veveysans (CEV), but not connected to that line.

The line to the boat landing stage was not originally built due financial problems and it was 3+1⁄2 years before it was completed, opening on 4 July 1915.

Following the road to the suburb of Tavel the line made its first crossing of the Clarens river and headed for Chailly, 2 km (1.2 mi) distant.

Following the road to just south of the village of Tercier when it left for a run on its own reservation until it reached the railway station at Blonay.

Talks to build a "joint" station with the CEV came to nought and the tramway built its own facilities to the rear of the main platform.

Overhead equipment, provided by Oerlikon (MFO), had a supply of 750 V DC, the same as the MOB at the time and the loading gauge had the same height and roof arc, but was slightly narrower.

These trailers were originally built in 1896[6] as part of a batch of Ce 1/2 cars for internal use at the national exhibition held that year.
