The services, suspended since March due to the coronavirus outbreak and the subsequent lockdown, will resume from June 29th in a joint effort between the Swiss Federal Railways (SBB) and Trenitalia.
The resuming train services will run in both directions from Italy to Switzerland.
To start with the services will run at 50 percent of usual capacity, with five lines to be reopened including the connections between Zurich and Milan and Basel and Milan.
Services are expected to run at 50 percent capacity until being expanded in mid-August and later to full capacity in mid-September.
The popular direct connection between Switzerland and Venice will start again in September.
