Moreover, line codes are not informative enough. Not every train are omnibusses
(actually, few of them are).

Talking about that, I guess it would be very useful to put up a collective
effort on that matter. First, we could collect the codes for every lines, and a
short description of the corresponding itineraries, then built a chart of every
stops for each codes. The result could be posted, or stay on my WWW page
(http://www.eleves.ens.fr:8080/home/cbonnet/trains/).

I volunteer for the RER C part. Other volunteers, please mail !

Je veux bien prendre en charge le RER B que je frequente regulierement,
mais je ne vois pas bien l'interet.

Je suis tres critique sur l'imbecilite du systeme d'information sur le
RER B. (Ce n'est pas vraiment plus ergonomique sur les autres RER me semble
t-il).
Les moniteurs tele recemment installes sont un net progres mais renseignent
toujours imcompletement le client (occasionnel) sur la facon de se rendre
a sa gare de destination.
Je m'explique :
Les principaux panneaux d'informations sur les destinations des trains sont
des panneaux 'lineaires' indiquant l'arret du train dans une station par une
lampe allumee en face du nom de station.
Ce panneau lineaire ne rend pas compte de la topologie du reseau qui est en Y.
De plus pour certaines origines destination comme Laplace -> Bures, il se peut
qu'entre 9h et 17h, aucun train ne fasse ce trajet. Plus d'un client
occasionnel
se fait avoir en attendant "le bon train" (en regardant les lampes allumees).
Rien ne dit que dans ce cas, il faut obligatoirement passer par une
correspondance plus ou moins pratique a Bourg la Reine (avec changement de quai
par souterrain une fois sur 2).

Des remarques et suggestions sur le RER, j'en ai a la pelle, si vous voulez.
Je fais aussi partie d'une assoc. des Usagers du RER de la vallee de Chevreuse;

I guess that was me... I should have saved it :-(

RER C:

1st letter is destination
A gare d'Austerlitz
B Bretigny
C versailles Chantiers
D Dourdan
E Etampes
G arGenteuil
J Juvisy
L Les invalides
M Massy-palaiseau
N montigny-beauchamp
P boulevard victor
R Rungis-aeroport d'orly
S Saint-Quentin en Yvelines
V Versailles rive gauche
Y dourdan + etampes (splits at bretigny)

2nd letter is stop pattern.
O for instance means that the train stops at all stations between Choisy
le Roi and Gare d'Austerlitz (POLO, VONY, SOLE, AOUT, GOTA, NORA, MONA,
ROMI, YOLE...). All other letters mean it doesn't. Didn't check out all
other traffic patterns, sorry :->

3rd and 4rth letter are only used to create a mnemonic.

Some examples:
AOUT, ANNE, BALI, JILL, CIME, VICK, VURT, VONY, SOLE, SARA, LARA, ROMI,
MONA, GOTA, NORA, POLO, YETI, YACK, YOLE, DUFY, EOLE...

Somebody already posted a list of codes on misc.transport.rail.europe
about a week ago. Who was that?

So this is the (original) purpose of the _second_ letter. In the original
idea (in the 70's for RER C this letter was there for making a difference
between omnibus, semi-direct and direct trains. "Unfortunately" with the
extension of codes to RER B, this became quite difficult due to the number
of different "missions" for the same terminus.

IMHO, actually only the first letter has some meaning for RER users (and
is quite difficult to remember as several letter are not the initial of
the terminus (think about P for St-Remy or E for Roissy airport..:-)

Was there an RER C in the 70s?!!

Maybe the P stands for Palaiseau, the first stop after Massy-Palaiseau ?

NON, la mission PJAB par exemple ne s'arrete pas a Palaiseau

Yes. I don't remember exactly (Christophe, do you know?) but the
Invalides-Orsay junction was achieved around 1977. The line was
immediately called RER C (the A line started before 1970 for the Etoile-La
Defense section and in 1970 for the St-Germain-Boissy East-West line...the
B line started between 1970 and 1975 by just renaming the Sceaux line).

If someone has the _exact_ dates, he/she will be welcome.

Maybe (but not probable...Palaiseau if too often confused with
Massy-Palaiseau). S was already used for C line train with terminus at
St-Quentin en Yvelines (SLIM, SVEN and so on...).

A note to thank you for this very interesting exchange. My son,
Stephen, translates the French for me, merci!

I rode the last rush hour train of the Boissy-St. Leger train a
vapeur in December, 1969. In March, 1970 I rode the original (?)
RER line to this same place. No mission codes were needed then, but
which are used on this line now?

Thank you very much for your help. -rwr-

The section of line between Paris Invalides and Gare d'Orsay was opened of september 30,1979.

There was a book about history of ligne C du RER "La Ligne C du RER" par
A. Jacquot, Editions de l'Ormet F-03330 Valignat, but I do'nt if it is still
available.
"La Vie du Rail" produced a book about la "Ligne de Sceaux".
