On 13 December 2009, the route was reclassified as the S8 suburban rail line. On 22 March 2010, service frequency was increased again, to bring services to half-hourly intervals from 05:00 to 11:00 and from 13:00 to 22:00 on weekdays.

Scheduling
, S8 trains ran hourly between 06:00 and 24:00 Monday to Saturday, with additional services during rush hour in the mornings and evenings.

As of 2024, S8 trains run every thirty minutes from Monday to Saturday up to late evening, when service becomes hourly; frequency is reduced to one train per hour per direction on Sundays. The last two trains of the day usually depart from Milano Centrale instead of Milano Porta Garibaldi, in order to catch passengers arriving with the last long-distance trains.
