Maybe it helps the driver to anticipate in the dark ?
But it doesn´t really make sense, why does the driver have to be noticed that there is a curve = low visability? He should notise sutch a simple thing, you don´t get a warning if you drive a car or a tram if there is a curve... All subway tracks i Paris are secured by signals aren´t they?

And I still noticed many bridges like Austerlitz and many viaducts on line 2 and 6 that are straight with these strange markings...

There is a huge visibility difference between a train tunnel (even on open sections just before a tunnel) and a road/open tramway where cars and trams run. Generally the latter have street lights or to aid the driver in seeing the bend and in some places road bends that are not easy to see are marked. Not so easy in a train where the track is unlit. Signals have nothing what so ever to do with it.

I would agree. Many of the tunnels are not well lit. This is not just in Paris, but other cities that have subway systems as well.

I see that some newer systems and lines tend to be better lighted than older ones in the tunnels, but idk if this is the case with all systems, lines, extensions built after 1990.

I don't know if you know the station Place de Clichy, a (very) busy station 400m far to Rome. 70% of the people using this station use it as a connexion between M2 & M13 (only 30% exit). Whith no interchange at Rome, they will NEED to stay on line M13, while a connection at Rome would be very helpful.

And Rome - Pont Cardinet, it's 750 m : people in Paris are older and older, so they won't leave the M14 at Pont Cardinet to keep line M2 at Rome !

So the both stations would be very intersting.

Boston and few other cities light there tunnels that have no divider between the tracks...

Yeah, I used to work there during 4 years (between Rome and Place de Clichy actually) !

IMHO if they chose Pt Cardinet over Rome for the interchange it's because of the new Batignolles area... And Rome is a bit too close from Pont Cardinet for creating a second interchange... just a guess about their choice.

what about the St-Lazare suburban lines ?

(this interchange would be much more easy than it is at St-Lazare, and it will certainly help to reduce the crowd changing at St-Lazare)

I guess the extensions to the M14 and the southern arc to be built by 2018 (indicated in red) will actually be built, but the later plans will depend on who holds political office in the future. In the end, the result may be more like the Arc Express plan and less like the Grand Metro plan.

Only if all the suburban service stop at Pont Cardinet, today only the L groupe III stop here.
Before the project of a metro station at Pont Cardinet, more trains services were planned to stop here but with this new station, it is not anymore usefull.

Pont Cardinet will be built to serve the Batignoles redevelopment area not to create a new interchange between Saint lazare suburban train and the line 14.

I am not against a station in Pont Cardinet, I am against the fact that there will not be any transfers between the line 2 and 14.
A big stupidity that will cost hundred of million in the future when when we will have to add a station, much more than if it was included in the beginning.

Planning errors are always very costly,

Well, yes I know that there is a visibilty difference between a train in a tunnel and road/tramway in surface mode, but trains do have headlights (I have noticed that headlights on Paris subway cars are poor). But there is still one big difference, cars/trams in streets are not allowd to run faster than they can stop if there is another vehicle or pedestrian in their way - a train/subway has a green signal and the track is clear and does not have to stop untill a station or a signal in danger mode. And if a track turnes the traindriver can´t do anything about it - if you are driving a car you can.

Having subway tunnels lighted all time is not so smart in my opinion. It only helps grafity painters to do a better job, just look at the tunnels in Paris...

Hope someone here from RATP can tell me about the mysterious red arrows and lines painted on the walls...

What a great day for the Ile de France region.

This expansion of Paris' metro will vault into perhaps the premiere transit system in the world.

Well, no need to add a station. As a matter of fact, they simply need to add an underground corridor equipped with moving walkways in order to connect the Ligne 14 at Pont Cardinet with the Ligne 2 at Rome (which would be much less expensive than adding a station).

The distance between Rome & Pont Cardinet is about 700 m (minus the station's length if the rear of the new station is between the two), which is quite comparable with the existing underground connection between La Chapelle & Gare du Nord stations for example (approx. 500 m).

That would require a complete systemwide upgrade to driverless trains.
