The contract follows on from the €20m first phase of the project, completed by Eurovia last year.
The second phase covers eight works packages involving the rehabilitation of the 33km network, and the acquisition of new rolling stock.
Modernisation of the tracks will be carried out gradually, with an emphasis on scheduling so as to limit as far as possible the impact on traffic in the city with its population of almost 250,000. Work will start at the end of this year and take two years to complete.
In all, Eurovia’s teams will work on 449 tasks. The rails will be entirely replaced and the utility networks affected will be re-routed. Electrical equipment, signalling, lighting and all tramway and bus platforms will be modernised. In addition, new information systems and a CCTV monitoring system will be installed.
