VGF has been constantly modernising its rolling stock since 2003 so it can offer passengers as modern a fleet as possible. Between October 2003 and March 2007, 65 S carriages were purchased from Canadian producer Bombardier Transportation (BT) at a cost of €113.8 million – all without receiving any subsidy from the state of Hesse. VGF currently operates a tram fleet of 103 vehicles that all feature low floors. What’s more, the S carriages are air-conditioned, and some of them are already equipped with video cameras, with the remainder ready to be fitted with cameras at a later date.

From 2013 onwards, VGF will be purchasing a further ten S carriages from Bombardier to run on the parts of the network that have already been extended (including the number 18 Frankfurter Bogen route) and on those parts that are currently under construction, such as the new stretch along the Stresemannallee. Together with the new underground trains that have also been ordered from BT, this amounts to a total investment of around €192 million.
