FART SA, based in Locarno, Switzerland, operates the narrow-gauge railway, with a gauge of one meter, from Locarno in the canton of Ticino through Centovalli to the Swiss border in Ribellasca, Italy. The catenary system is a maintenance-intensive catenary system that dates back to the 1950s.
EUROPTEN Schweiz AG has been commissioned with the renewal of the catenary system in the stretch section S. Martino to Ribellasca (rail km 3,200 to 18,900).
The existing catenary will be replaced by a semi-retrained system, and the existing catenary support points outside the stations and the Galleria Paramassi will be completely renewed except for individual masts. In addition, a continuous return conductor of 1x95 sq mm and a supply cable with 2x95 sq mm should be laid on the entire section. The bases used are isolated steel poles with an HEB profile.
The project will be realized in seven stages in the years 2018 - 2023.
