Not so easy. That's right for lines like the line 1 that runs under very wide streets. But most of the time, space is very scarce on the ground in Paris and there's simply not enough place available to build ventilation shafts.

Moreover, ventilation in the subway in Paris has always been an issue because of the small diameter of the tunnels and the lack of space between the tunnel and the roof of the trains.

Another major issue is the water. The soil in Paris is saturated with water. More heat in the tunnel means more humidity in the air (humidity is already unbearable in summer on rush hours).

Some trains are rubber-tyred. Tyres diffuse more heat. As an exemple, that's why the line 4 is so hot... and not climatised.

For all those reasons, the RATP has always been very reluctant about climatisation.


I took some pictures last week during the heritage days.

The oldest trains, made of wood. They were removed after the disaster in the station Couronnes (more than 80 people killed) :



The structure of those trains was reused to build the new trains, however ; that's the reason why they look partially build of wood and partially of steel (they were replaced in the 30's) :



A Sprague-Thomson in use on the Nord-Sud network (replaced in the 70's) :



A first-class trailer :



A parisian icon... A Sprague-Thomson of the RATP :



Another one with wooden doors (the last Spragues were removed from commercial service in the 80's : but many were converted in mobile workshops who were in use until... 2014 : you can see one of them in the background) :



The logo of the CMP was painted everywere inside the trains and was never coated or removed :



More to come !

Does anyone know what RATP plans to do with the rolling stock that's currently used by Line 4 once this line is converted to driverless operation? IMO those trains would be a good match for Line 6, whose rolling stock is badly in need of replacing.

For now line 4's rolling stock is intended to line 6.

That is very good news! For the uninitiated, this station is just next to the largest shopping district for African people in Paris. It's bustling with people to the point where the entrance and exit are sometimes jam-packed and one fears that somebody will be trampled or squeezed badly. This expansion should have happened 10 years ago but, well, better late than never.

If New York, Camden, and Philadelphia can do it, I am sure Paris can as well.

Ah yes, regarding line 13 I have a question. (I seem to be turning into our "inhouse expert" on stupid questions...) As most of us know, RATP have installed platform doors on all stations from Montparnasse-Bienvenue northwards. I thought initially that this was in preparation for a automation of this line (= driverless service), but I am informed that this is not going to happen. So, what are the purpose of those doors - crowd control? It must be recognised that the northern part of that line (or PARTS - there are two) is very crowded, and one could imagine that during the rush hours the train's own doors would get forever jammed by people trying to squeeze in.

Yes, crowd control.
Actually, it is primarily a measure of security and improvement of the train approach speed in busy stations.
It greatly reduces the number of people failling or trespassing on the tracks.

The frequentation of the metro was extremely high during the german occupation of Paris and the maintenance was insufficient.

After 1945, lack of money and priority given to the production of automobiles led for the first time in the history of the subway to a fall of this frequentation.

Only two attempts were made in the 50's to modernize the network.

The MP 51, nicknamed "grandma", was a single prototype of rubber-tyred metro :







It was tested as a shuttle between Pré Saint Gervais and Porte des Lilas (this short line is now closed but it could reopen in a distant future in case of a merging between the line 7bis and 3bis). It was so reliable that the RATP decided to open the shuttle to the public.

The MA51 (A for "articulated"), on the right, was the first new rolling stock built for Paris. Only a handful were made (I remembered them very well ; I used them often on the line 10 ; the seats were made of cast iron and for this reason, they were nicknamed "bathtubs" ).



As the MP51 was a technical success, a whole line was converted for rubber-tyred trains and the MP 55 was put in commercial service.





They are now retired but they were very similar to the MP 59 later built for the line 1 and which are still in service.

No, during the heritage days, last week.

People can see those vehicules only two days a year.

Sadly, such a museum for public transport does not exist in France, for several reasons. Some vehicules are owned by the RATP. But most of them are the property of the AMTUIR, a private association. This association did a fantastic job to save many historic tramways and busses while the authorities were absolutely not interested. There's no space available for a museum near Paris ; but most of the members of this association are parisians who refuse the delocalisation of the collection.


When the decision was made to build the RER, the real renovation of the metro began. This is the prototype of the MF 67 ; it was made of stainless steel ; as as it doesn't rain very often in tunnels, the following trains were made of standard steel.

A bit strange to say there's no space for a museum in the close proximity of Paris. There's plenty of land, but I would see how the funding would be a problem.

Métro Porte de Saint-Cloud by Tim Boric, on Flickr

This looks like a very large siding at Porte de Saint-Cloud. Is there something like a special service during football matches with additional trains?

€ 90.000.000,00 is too much for A simple but stylish museum where people can see and experience Public Transport vehicles?

If Ratp & Stif would be willing to cooperate and attach the museum to A tramline & part of the Metro. People could make trips in historic trains/busses based on A special fee, dining or having A lunch could be possible, or having A marriage/married couple travel.

The vehicles could also be used in movies.

Might be A good idea to setup A facebook page and start A lobby.

Having massmedia focused on A vast lobby might help financing it ;-)

Panels to cover water infiltration used on wide scale in one of the corridor linking the metro to the RER at Saint-Lazare

A special service was planned for the Parc des Princes but has never worked.
A tunnel linking the line 9 with the line 10 with a station next to Parc des Princes was built. Porte Molitor.

I wished they would think about doing this in Vienna at some stations too.
Guess things like, more people falling or trespassing on the tracks, have to happen here first before they even consider this.

Funding approved for Paris projects
09 Oct 2015



FRANCE: Meeting on October 7, the board of Ile-de-France transport authority STIF unanimously approved a framework agreement to fund the extension of Paris metro Line 11 by 6 km from its current terminus at Mairie des Lilas to the RER Line E station at Rosny-Bois-Perrier. Costing a total of €1⋅3bn, the project will add six new stations to the network, serving a population of 82 500 within 600 m.

Construction of the extension has been budgeted at €1⋅08bn, of which the French government is providing €214⋅4m, the Ile-de-France region €500⋅3m, Société du Grand Paris €305⋅3m and the département of Seine-Saint-Denis €64m. A first tranche of €110m has agreed for the initial phase of works, being provided the government, Ile-de-France, the département of Paris and RATP

I love all these plans for extending métro lines with a few stations. There are a few such other prolongations that I would like to see, but the one in which I have a vested interest would be the prolongation of line 3 with one more station towards Bécon - Les Bruyères, where it would meet not only line L but also line 15 of the GPExpress.
