Trains have been running through the Gotthard Base Tunnel since earlier this morning, without any problems affecting what is a historic timetable change along the north-south Gotthard corridor. Passengers and freight customers are benefiting from shorter journey times and more reliable connections. Two special early-morning trains took customers and guests to Lugano, which is celebrating the opening of the longest railway tunnel in the world and also of its own refurbished station. The timetable change ran also largely without problems in the rest of Switzerland.
