After I red some information, yes the RER A have express service.
_____________________________________________________________






RER A is Europe's busiest line with over 1,000,000 passenger/day. Line A is formed from the connection across Paris of the Saint-Germain-en-Laye-Nanterre line in the west to the Vincennes — Boissy-St-Léger line in the east. Two branches were added in the West, to Poissy and the 'ville nouvelle' of Cergy, and another in the East, to the ville nouvelle of Marne-la-Vallée. The two latest extensions of the line were to Cergy-Le Haut and Disneyland Resort Paris.

Line A has been a runaway success since its inauguration and has now over 60,000 passenger per hours in rush hours
Ever-increasing traffic volume and the need to ward off imminent saturation have been major factors in RATP and SNCF's planning since the inauguration of the Line A. At least five major capital investment decisions can be directly traced back to this issue:
  • In the early 1980s RATP contracted German conglomerate Siemens to develop a dynamic traffic control system that would remove the capacity constraints caused by conventional block traffic management. This system, called SACEM (Système d'aide à la conduite, à l'exploitation et à la maintenance), remains today one of the world's most advanced traffic control systems and enables extremely short spacing (under 90 seconds in stations, under 2 minutes in tunnels) between trains during rush hour. (Parisians have become used to the sight of a train pulling into a station as the one before it is just clearing the platform.)
  • Around the same time, RATP had to order a significant number of additional MI79/MI84 trains to remedy premature wear and tear on its existing MS61 rolling stock caused by over-utilization of Line A.
  • Later in the 1980s, the need to relieve congestion on the central segment of Line A was a key factor in selecting the route of the new, fully automated Line 14 (also known as METEOR) of the Métro.
  • The same need governed the choice of the route of RER Line E in the early 1990s and is a factor in current plans for that line's westward or south-westward extension.
  • An entirely new class of double-decker trains (MI 2N series) entered service in 1998, in part a product of RATP's belief that no further infrastructure improvement (short of an extremely expensive track quadrupling) would relieve congestion on Line A.
One simple (if partial) solution to the congestion problem that has never been implemented is a change in the seating configuration inside the trains themselves. The RER is unusual among high-capacity urban train networks in its attachment to "transversal" (front and back facing) seating. A change to "longitudinal" (sideways window-lining) seating typically reduces the number of seats by 10% but increases standing room by 30%. The result is increased capacity and a less cramped ride for those without seats.

The D line is long as hell! I never knew that, how long does it take to go from one terminus to the other?

I am not sure that you can.

The RER D is the longest (160 km) and the worst RER line.
It is called the trash RER,
Information in french Here

This cheap RER line have big exploitation problem, it use the busy RER B tracks between Chatelet and Gare du Nord and have a high irregularty rate with low frequency.

For me it is not a real RER line.

It also has the worst rolling stock in my opinion (the Z20500 EMU).

Line B was the product of the connection in 1977 of the Ligne de Sceaux terminus, Luxembourg, with the Gare du Nord via Châtelet - Les Halles. In 1988 St-Michel - Nôtre-Dame station between Luxembourg and Châtelet - Les Halles was opened to provide connection with RER C and Métro Line 10 at Cluny - La Sorbonne, a station which had been closed since the beginning of the second world war and was entirely renovated for the occasion.

The southern part of the line (south of Gare du Nord) is operated by RATP, the northern part by SNCF. Trains are owned by either company. Drivers change at Gare du Nord. Trains moving from one network to the other at this station is known as the Interconnexion. Technical difficulties of the interconnection include: the shared tunnel with RER D between Châtelet - Les Halles and Gare du Nord, and the fact that while the northern suburbs use 25 kV AC current, the RATP part uses 1500 V DC, forcing the use of dual-voltage trains.

With 850,000 passengers per day it is the second busiest line in Paris

The southern part is really beautiful.
I live not far of it.

Isn't Moscow's Tagansko-Krasnopresnenskaya line (purple line) the busiest?

Actually, this would deserve to be double checked.

We have only old and partial data for the RER A. The 273 million annual trafic figure in 2004 excludes the SNCF sections of the line (branches to Cergy and Poissy). Furthermore, traffic has massively increased on the RER in the recent years (mainly due to Deloanöe's policy to limit automobile traffic). Finally, datas for the Moscow metro are about daily ridership whereas those of RER are about annual ridership, and the conversion between both figures isn't that easy.

Well, all this to say that Moscow's purple line may be busier than the RER A, but this is really not sure.

Well, thanks, I'm also a big fan of lines A and B, though I must admit it's probably not the best period to admire them currently.

I've often talked with pride about the high frequency of trains on line A, but currently, there's really not much to be proud of...

And there is not traffic in the southern RER B.

The RER C is so confusing, I think they should simplify it by connecting it to the RER E and extend the RER E from Haussmann - Saint Lazare and make a new branch (or two).

[email protected] is right, the RER E has other extention projects.
One is bad and cheap and an other wich is better but more expensive.

In several long years (It is not exagerated to say 20 with the actual goverment of Paris region) the southern branch of the RER C (C8) Juvisy sur Orge to Versailles Chantier should be deconned of the RER C and would became a part of one of Grand Ceinture (Outer ring) lines.
