[14] From 1917 onwards, the Swiss Peat Co-operative (Schweizerische Torfgenossenschaft, S. T. G.) exploited the 50 hectares of peatland leased from the Société Anonyme des Marais des Ponts near Les Ponts-de-Martel.

The narrow gauge railway tracks with a gauge of 600 mm (1 ft 11+5⁄8 in)} were partly made from portable Decauville rails, partly from permant rails on wooden sleepers.

The transports from the dry fields to the loading ramp and to the peat sheds were done by hand in 1918-1919.

In 1920, to increase efficiency, a 600 mm gauge tractor with an Austro-Daimler petrol engine was purchased, for which a small shed was built on the peat field.
