Stadtwerke Potsdam awarded DPP a contract to refurbish 12 vehicles in May 2016 following a European tender.
Modernisation of the fleet is intended to extend the life of the vehicles by eight years or 800,000km. The 17-month programme includes the replacement of floors and an exterior repaint.
Potsdam has opted to upgrade its Tatra trams as a quick and cost-effective response to rapidly-increasing ridership on the tram network. The work is being carried out as part of a €50m project to upgrade and expand the network.
