Santhià–Arona railway

The service on the railway was suspended from 17 June 2012, by decision of the Piedmont Region.^[3] At the time of its closure, the line was served by sixteen trains per day on weekdays and six on weekends, with an average use of fifty passengers per train.^[4]

At a meeting in September 2019, a representative of the regional council declared that reopening the line was not financially viable, costing 3.4 million euros more than a bus replacement service.^[4] In response, an association for the Turin-Switzerland line stated that the council's decisions, while correct from an accounting perspective, threatened the socioeconomic development of the region.^[5]

In January 2022, it was reported that the regional government was prioritising the reopening of the line in talks with FS.^[6] In November 2022, it was announced that the line would be reopened by 2024-25, following a campaign by Alberto Gusmeroli, a deputy for the Piedmont 2 constituency.^[7][8]
