The contract to supply the RER NG (New Generation) fleet has an estimated value of around €3.7bn. The first trains are due to enter service in 2022 on RER Line D, where they will replace Z 2N double-deck EMUs dating from the 1980s.

CAF France general manager Mr Francis Nakache told Agence France Presse on November 2 that the company had received a letter from French National Railways (SNCF) advising that it would not be required to submit a final offer because of a “negative assessment” of its capability to produce the trains in line with the requirements of the tender.

SNCF is managing the procurement on behalf of Ile-de-France transport authority Stif, which is funding the order.

A winning bidder is due to be announced early next year.
