The line S12 (it|Linea S12) is a commuter rail route forming part of the Milan suburban railway service (it|Servizio ferroviario suburbano di Milano), which converges on the city of Milan, Italy.[1]
The route runs over the infrastructure of the Milan Passante,Milan–Bologna and Milan-Asso railways. Like all but one of the other Milan suburban railway service routes, it is operated by Trenord.
Line S12, a cross-city route, heads initially in a southerly direction from Milano Bovisa through the Milan Passante railway to Milano Rogoredo. From there, it turns south-east towards its southern terminus, Melegnano.[2]
The route was activated on 12 September 2016.[3] The route was suspended on 25 February 2020 due to COVID-19 pandemic[4] and it has been partially restored in August 2023, with four trains per direction per day, running at 15 minutes intervals when paired with line S1.[5] A more complete service shall be restored in 2024:[6] since June 2024, service has been expanded, with 10 round trip per day from Cormano-Cusano Milanino to Melegnano and one round trip per day between Cormano-Cusano Milanino and Milano Rogoredo; this has been made possibile by the construction and opening of the third track from Milano Affori to Cormano-Cusano, allowing for more separation between regional trains, which run express from Affori to Cesano Maderno, and suburban all-stopping trains.[7]
