The option is part of a contract signed in 2007 and brings the total number of LRVs ordered to 104. So far the consortium has delivered 77 vehicles to Manchester.
"The new Flexity M5000 vehicles are helping us deliver greater capacity and a much more reliable journey, with lighter, brighter and more spacious interiors giving extra room for passengers," says TfGM's director Mr Peter Cushing. "We look forward to completely replacing our tram fleet with this model during 2014."
The Manchester Metrolink light rail network is being steadily expanded. The network is currently 76.8km long with 73 stops. Three extensions are under construction to the airport, through the centre of Oldham and to Rochdale Town Centre, with more planned.
