The site is not yet finished but when you start to see trains running, it's a pretty good sign, rejoice the representatives of the RATP and Île-de-France Mobilités.
The vibrato of the MP14s mingled with the noise of backhoe loaders and dump trucks, this beginning of the week, to finalize the test phase of the viaduct, located between the future Coteaux Beauclair and La Dhuys stations, on line 11, at the height of Noisy-le-Sec (Seine-Saint-Denis).
The extension of line 11 continues on its way.
Without untimely schedule slippage, unlike some projects.
“In the current context, we must always remain cautious, underlines Pierre Florent, the director of the extension of line 11 for the RATP.
But commissioning is scheduled for the end of 2023.”
For the time being, tests have been carried out on the short kilometer of the viaduct, which spans "the A3, the Coteaux, the motorway interchange to come and dive into the motorway junction at Rosny 2", explains
Stefano Contaldi, the civil engineering project manager for the RATP extension.
See if the viaduct does not bend too much
Loading, statistical and dynamic tests took place on Tuesday and Wednesday.
“It's the last step in building a bridge,” continues Stefano Contaldi.
This allows you to see if the structure respects a certain behavior, how it bends, when the trains pass.

These making round trips without a traveler, but with "pigs", simulating the weight of the passengers.
Attached to the viaduct deck, wires weighted with a weight then measure its bending, to ensure that the installations are not called into question.
The MP14s will then return to the workshop and will not come out until the beginning of December, where they will carry out “dynamic tests on the already existing line 11, between Châtelet and Mairie des Lilas, without passengers”, specifies Pierre Florent.
And in a short year, the MP14 will connect Châtelet to Rosny-Bois-Perrier, by “improving the quality of travel for historical users, underlines Arnaud Crolais, the director of infrastructures for Île-de-France-Mobilities.
It's a time jump.

The oldest RATP trains, the MP59s, currently running on the line will all be replaced and scrapped.
The metros will follow one another every 105 seconds, with an additional train, in order to accommodate more than 25% of passengers, explains Pierre Florent.
Going from a capacity of "50,000 passengers per day to 85,000", and offering a connection with the future line 15 and the RER E. But still a little patience, four stations remain to be built.
