Alstom to equip Paris region commuter rail lines with signalling technology

146 MI20 trains to run on the RER B line Île-de-France Mobilités

Several weeks following the inauguration of the RER NG (New Generation) train for the RER D and RER E lines in Île-de-France by Île-de-France Mobilités, SNCF Voyageurs, and Alstom, Alstom has secured a €300 million contract for the implementation of NExTEO signalling technology on two Réseau Express Régional (RER) lines in the Île-de-France region. This extensive 12-year framework contract stands as one of the most substantial signalling contracts ever awarded in France.

Under this agreement, Alstom will develop and implement the NExTEO train automation, control, and supervision system on the RER B and RER D lines in Île-de-France, catering to Île-de-France Mobilités, SNCF Réseau, SNCF Voyageurs, and RATP. Jean-Baptiste Eyméoud, President of Alstom France, revealed that a total of 350 trains and 100 kilometres of these two RER lines, known for their high traffic volume in Île-de-France, will be equipped.

The NExTEO Communications-Based Train Control (CBTC) signalling solution is a key component of a comprehensive strategy aimed at modernising and optimising the infrastructure of the RER B and RER D lines. The goal is to accommodate the rising ridership, enhance the reliability of train passages in the common tunnel between Gare du Nord and Châtelet-les-Halles stations, and improve performance in central Paris while adapting to less densely populated suburban areas along the RER lines. Moreover, the technology facilitates simultaneous control of operating and interoperability rules on both the SNCF National Railway Network and the extensive RATP urban network, particularly on the southern segment of the RER B line.

Alstom’s Urbalis signalling technology will also contribute to enhancing the performance, punctuality, and throughput of RER lines B and D in response to the escalating passenger traffic. Leveraging the expertise of Alstom sites in Saint-Ouen and Aix-en-Provence, this encompasses on-board CBTC equipment and trackside signalling products.

Future proofing, yes, but railway infrastructure, in no respect is future proof. (Safety factors are missing at railways.)
Contemporarily, all other modes, as redundant, as benefitting of surplus capacity, decisively upgrade, for added load and lower costs. (At railways, however longer trains is single option…)
At any investment, STAX32 (a 40 %, added load capacity) should be min., as for a marginal extra, available – and affordable.
(Weak Link has to be attended!)
