Tunnelling begins on Paris metro extension
Wednesday, September 09, 2015



TUNNELLING was officially launched on the 5.8km northern extension of Paris metro Line 14 from St Lazare to Mairie de Saint Ouen on September 9, when the project's first tunnel boring machine was christened Magaly

The ceremony was attended by French transport minister Mr Alain Vidalies, the mayor of Paris Mrs Anne Hidalgo, president of Ile-de-France regional council Mr Jean-Paul Huchon, and Paris Transport Authority (RATP) president Mrs Elisabeth Borne.

The extension will relieve the heavily congested section of Line 13 north of St Lazare and has a design capacity of 40,000 passengers per hour. It will interchange with RER Line C, Transilien (suburban) Line L, and light rail Line T3b

A old documentary of 1996 about Paris Metro



We can see clearly the transition between the old blue color and green livery
I didn't know that there were trains with the two liveries.


MP 55 on line 11


Unrefurbished MP 59 on line 4


MF 77 on the line 13 were still white

Bonne nouvelle
Note: Bonne Nouvelle means good news in French
Bad news, because of a serious accident involving passenger at Nation (passenger failing in the tracks hit by train, this how it is called by the RATP accident grave de voyageur), the traffic is interrupted on the eastern side of the line from Oberkampf.
This disrupted traffic to the east with a jam of train beginning several stations before Oberkampf.

Despite the red headlights, this is the front of the train. The train is just stuck here waiting.

After several long minutes of wait, the train is allowed to depart.
You can see that the headlights turn white.

The tunnel boring machine for the extension of line 14 from Saint-Lazare to Saint-Ouen has been installed at the future Pont Cardinet station:



It's going to excavate the part between Pont Cardinet and Saint-Lazare first, then the part between Pont Cardinet to Saint-Ouen. This other video, completely rendered, is fantastic at showing how exactly the whole process is going to happen:

Well. if, according to this video, second TBM phase will bore between Pont Cardinet to Saint-Ouen, how about provisions for Saint-Ouen-Saint-Denis Pleyel section boring?

Two TBM will be used for the extension from Saint-Lazare to Mairie de Saint-Ouen.
The first TBM will bore between Saint-Lazare to Clichy in two phases.
A second TBM will bore the rest of from Clichy to Saint-Denis, also in two phases.



For the latter extension to Saint-Denis Pleyel, I don't know. I imagine it will be at Saint-Denis Pleyel.
There is a lot of space there and they will build a big interchange station.
The perfect place to launch the TBM.

There were plans for interchange at Rome station, but as I understood it was dropped due to costs or overcrowding problem

To make it a much faster alternative to line 13, which is the one that needs relief?

Paris Line 18 contract awarded

But it is forgetting that Place de Clichy, the interchange between lines 2 and 13 is the third busiest station on line 13.
A lot of people transfer between both lines.

I heard that at the beginning of line 14's planning, many thought that the transfer between line 6 and 14 at Bercy was not necessary.
When you see how busy Bercy is during rush hours, they were clearly wrong.

Every point of two lines crossing but not having interchange is wrong. I thought its so obvious for everyone. But as we can see it is not.

Seems you are wrong. Completely underground lines need to have much better ventilation / air conditioning right because they are underground. In the world there are hundreds of examples of that, just take Asian metro systems. Underground lines are not hermetic so, the heat needs to be taken out through powerful systems of ventilation, too.

An overground, in return, has an advantage of natural. Entilation and as a result needs cooling to a lesser extent.

I remember that the mayor of Paris Anne Hidalgo promised that the metro of Paris would become a 24 hours metro ( http://www.leparisien.fr/politique/m...15-4521371.php ). Is it a real possibility ?

It is not being considered by STIF for now.

Yes, but I fail to see why that means that I'm wrong. Modern metros like the one they're currently building in Beijing have massive ventilation shafts. - Which, as you say, enable industrial - scale air conditioning. But older systems like Paris and London don't have that. In fact, each time the British press (which is considerably harsher on politicians than what we have in Paris) raise the demand for an air conditioning of "the tube", the operator company raises its hands and exclaims that it would then have to spend billions of Pounds on retro - fitting ventilation shafts.

Unlike the Tube, Paris metro tunnels are close to the ground, it is relatively easy to build ventilations, what the RATP is doing in places where those don't exist.
