Ensure the implementation of the operation's plan (which translates to the customer in the circulation timetable) set for the Oporto Light Rail System is our top priority. In recent years, compliance rates of the operation plan were always above 99%.


ViaPorto ensures all everyday preventive and corrective maintenance of vehicles (Tram-Train and Eurotram fleets) and fixed installations (infrastructure, equipment and stations and technical signalling and operation support systems), general cleaning and landscaping services of the Metro do Porto network. The activity developed by ViaPorto made it possible to achieve over the last few years high levels of availability (vehicles and equipment), which has been critical to the proper functioning of the Oporto Light Rail System.
