[11] Inaugurated in April 1907, the network consisted in a 1,000 mm (3 ft 3+3⁄8 in) line stretching across the town centre.

[12] The energy was supplied by a power plant built by Mr Ravous, a building contractor from Granville, and located near the Avranches station.

The track and the switch connecting the two lines had been laid, but a fault in the switch had caused an accident in March 1907, when the Avranches to Saint-James tramway ran onto the track of the electric tramway towards the station, causing the derailment of a car at the end of the train.

[18] As the Société des chemins de fer de la Manche operating the electric line and the Compagnie des tramways normands operating the tramway from Avranches to Saint-James were initially unable to agree on how to operate the section together, the electric line ran initially only to Octroi du Centre.

[6] By October 1909, the line was extended from Octroi du Centre to the Avranches–Saint-James tramway terminus.
