Tramways, clean transport in the heart of metropolitan areas
Although trams had almost disappeared – especially in France in the middle of the 20th century – supplanted by the automobile, the bus, and the metro, trams have once more become a preferred means of transport in the heart of cities.
After the Second World War, tram lines were gradually removed to make way for the automobile. In France, for example, of 48 cities with tramways, only 3 retained them (Lille, Saint-Etienne, and Marseille).
At the end of the Seventies, several factors allowed tramways to regain their place in the heart of cities: the oil shock, the struggle to reduce traffic congestion, environmental concerns, and decentralisation, which made local authorities responsible for organising public transport. Clean and quiet, they are now in service in more than 25 cities in France. Elsewhere, as in the USA, San Francisco has never abandoned the tramway it created in 1891, whereas Salt Lake City, Tucson, and Phoenix have all installed them more recently.
VINCI Energies participates in tramway development
The business units of VINCI Energies deploy their expertise during the different phases required to complete a tramway, in France as well as abroad, in cities such as in Prague, Berlin, and Gothenburg.
The business units install temporary and permanent public lighting systems along future transportation infrastructures. Their work is performed concurrently with the rerouting of gas and water mains. Most of these business units are under the Citeos brand, which in France participates in the installation of lighting networks, as in Paris and in Orléans.
Nextram: your tramway within reach
VINCI Energies is part of the consortium developing Nextram, a turnkey offer to construct tracks and provide trams. More economical to install than a conventional tramway, it allows medium-sized cities to equip themselves with sustainable transport.
Once the infrastructure is in place, equipment to provide electricity is installed to be able to power the trams, as in Rabat and Casablanca in Morocco. The operation consists in deploying overhead contact lines (LAC) carrying a continuous current of 750 or 1,500 volts, and to connect them to electrical substations which in turn connect to the EDF electrical grid.
VINCI Energies has also developed a unique system to permit tramways to consume less electricity by recuperating energy generated by braking.
