Transdev S.A.

Transdev was an international public transport group based in Issy-les-Moulineaux near Paris, France, and operating in several countries. Originally created as Société centrale pour l'équipement du territoire in 1955 and developing transportation activities since 1973, Transdev was a subsidiary Caisse des Dépôts et Consignations, a French state-owned financial institution. On 3 March 2011, the group merged with Veolia Transport, one of its main competitors, into Veolia Transdev. During 2013, Veolia Transdev was renamed Transdev, recognising the planned withdrawal of Veolia Environnement from ownership of the group.

As part of this merger, the RATP Group, a minority shareholder in Transdev, took direct ownership of a number of former Transdev operations in lieu of a cash payment.

Transdev was also a shareholder of Transamo, a transport engineering and consultancy firm in Europe, which specialises in the project management of public transport projects in France. It was passed onto Veolia Transdev after the merger. Société de Transports intercommunaux de Bruxelles (STIB) is the other major shareholder of Transamo.
