On June 30th & July 1st 2022 the 6th TSO Forum will take place in Brussels (Belgium). The central theme, tunnel refurbishment, will be highlighted by relevant presentations, workshops and lively discussions. The event will start at Thursday morning and includes an afternoon site visit and a joint dinner in the evening. On Friday morning we continue with lectures and we close the event with a lunch. Of course, there will be plenty of time to meet and greet other TSO’s!
