The RER line D is one of the most important north-south connections for suburban Paris traffic in the Île-de-France region . It connects Orry-la-Ville-Coye (D1) and Creil (D3) in the north with Melun (D2) and Malesherbes (D4) in the south. It crosses the capital and meets important junctions such as the Gare du Nord , the Gare de Lyon and the central interchange station Châtelet - Les Halles .
Line D is 197 km long, some of its stops, such as Malesherbes in the south and all stations north of Survilliers-Fosses are already outside the Paris tariff system. It is fully served by the SNCF .
history
- In 1987, line D only began operating on the northern branch from Châtelet - Les Halles to Villiers-le-Bel. In sections until 1990 the extension to Orry-la-Ville and Creil and thus the northern part was completed.
- It was only in 1995 that a tunnel between Châtelet - Les Halles and Gare de Lyon was opened to the south. The terminus was initially La Ferté-Alais station , and RER trains did not run through to Malesherbes until a year later.
- In 1998 the line was upgraded with the opening of the station at the Stade de France .
- In 2010, the line in the Seine valley between Corbeil-Essonnes and Melun was included in the RER plan. In 2014, the frequency of trains on this route was up to four trains per hour during rush hour and one train per hour outside.
- In 2013 the newly built Créteil-Pompadour station was opened and instead the Villeneuve-Prairie station , which was only a few hundred meters away, was closed. By relocating the station, line D was connected to the express bus lines Trans-Val-de-Marne and RATP 393 , creating a cross connection to the terminus Pointe du Lac of line 8 of the Paris Métro .
Route
Overview: The RER branches and their history
Northern branch
To the north of the capital, the line runs past the Stade de France and through the city of Saint-Denis . The main branch D1 ends in Orry-la-Ville -Coye and this is where most of the trains heading north end. This is followed by the route to Creil ( D3 ), which actually has only a small number of passengers, but is still served by line D.
The Paris-Gare du Nord - Saint-Denis line was built as early as 1846 as part of the Paris - Lille line; the Saint-Denis - Creil section was opened in 1859.
Paris
First, line D shares a tunnel with RER line B from Gare du Nord to Châtelet - Les Halles, which went into operation in 1981. This leads to major problems and requires logistical masterpieces every day during rush hour. It then runs - in its own tunnel, completed in 1995 - parallel to RER line A to Gare de Lyon .
Southern branches
South of the Gare de Lyon, the line initially runs to the right of the Seine until it splits at Villeneuve-Saint-Georges station . D 2 Melun via Brunoy : On the one hand, an eastern branch leads to Melun via Brunoy and Lieusaint-Moissy . The line from Gare de Lyon was commissioned as part of the Paris - Marseille line between 1847 and 1855.
D 4 Malesherbes / D 6 Corbeil-Essonnes and Corbeil-Essonnes / Melun :
The western branch leads via Juvisy (the only transfer station between RER D and line C ) to Viry-Châtillon , where there is another junction: the D 6 is a route in the Seine valley via Èvry to Corbeil-Essonnes . On another route via Orangis - Bois de l'Épine , line D 4 also reaches Corbeil-Essonnes , which branches off again there: Malesherbes can be reached via one branch ; over the other one comes - in the Seine valley - to Melun .
The line Villeneuve-Saint-Georges - Corbeil-Essonnes - Malesherbes is part of the long-distance line Villeneuve-Saint-Georges - Montargis and was built in the years 1840-1867.
In 1897 the line was created in the Seine valley between Corbeil and Melun as part of the Corbeil-Essonnes - Montereau-Fault-Yonne line .
The Grigny - Évry-Courcouronnes - Corbeil-Essonnes line is also very young: it was opened in 1974/75. It was the first line of new construction since the SNCF was founded. With this line, the ville nouvelle of Évry should be developed for traffic.
2018: Shortening of the RER route network in the south and reorganization of train traffic:
As part of the so-called Service Annuel 2019 , which specifies the timetable for 2019, two routes will be removed from the RER D area with the timetable change in December 2018:
- The traffic on the Juvisy ↔ Malesherbes route is carried out with shuttle trains and only runs in the Seine valley, i. H. via Ris-Orangis.
There are no longer any direct connections with Paris from / to Malesherbes.
- The traffic from Melun in the Seine valley ends in Corbeil-Essonnes.
- The western route Juvisy ↔ Corbeil-Essonnes via Orangis, however, remains in the RER and the number of trains to / from Paris is doubled here.
The aim of this operation is to improve punctuality on the RER-D network, because 25% of the delays in the entire network are due to the complicated route or train routing in this section.
The railway stations
Infrastructure
Power supply
For historical reasons, the route network of the RER D is divided into two parts with regard to power supply:
The northern part, like the entire northern network area of the SNCF, is supplied with an operating voltage of 25,000 V. The lines in the underground part of the Gare du Nord are operated with two different voltages: The tracks in the north-south direction of the RER lines B and D are supplied with 1,500 V; the tracks in south-north direction with 25,000 V alternating current.
The Gare du Nord - Châtelet-Les Halles section is part of the RATP network and is operated with 1,500 V DC, as are the SNCF lines south of Paris. The AC voltage in the RATP network is better smoothed than in the SNCF network.
This dichotomy of the network made it necessary to use two-system vehicles.
Train names
On the Parisian RER trains, the destination and route of the trains are indicated by four letters, each of which forms a (fancy) name. The following letter combinations are used in the RER D:
The first letter: It gives an indication of the terminus:
- A = Gare du Nord
- B = Malesherbes; Line D4
- D = Gare de Lyon
- E = Saint-Denis
- F = Goussainville
- J = Juvisy
- K = Evry - Courcouronnes
- L = Orry-la-Ville - Coye
- M = Châtelet - Les Halles
- N = Combs-la-Ville - Quincy
- Q = Villeneuve - Saint-Georges
- P = Créteil pompadour
- R = Corbeil-Essonnes
- S = Creil
- T = La Ferté - Alais
- U = Stade de France - Saint-Denis
- V = Villiers-Le-Bel - Gonesse - Arnouville
- Z = Melun
The second letter : It describes the behavior of the train between Paris-Gare de Lyon and Villeneuve-Saint-Georges.
- A: The train stops in Maisons-Alfort-Alfortville and Créteil-Pompadour
- I: no stop between Paris-Gare de Lyon and Villeneuve-Saint-Georges
- O: Train stops in Maisons-Alfort-Alfortville, Vert-de-Maisons, Créteil-Pompadour and Villeneuve-Triage
- U: Train only stops in Maisons-Alfort-Alfortville
The third letter : Five different letters are used here. They indicate which branch the train is taking and whether the stations of the branches are served via Évry-Courcouronnes or Ris-Orangis.
- C: Train runs via Combs-La-Ville - Quincy
- L: The train only runs the Creil ↔ Juvisy section
- P: (P stands for plateau = plateau) Train travels on the Évry-Courcouronnes branch
- R: Train does not stop between Corbeil-Essonnes and Viry-Châtillon
- S: (S stands for Sud) Train only runs between Malesherbes (or La Ferté-Alais) and Corbeil-Essonnes or only between Melun and Corbeil-Essonnes
- V: (V stands for Vallée = (Seine) Valley) Train travels via Ris-Orangis
The fourth letter : Three different vowels are used to provide information about the direction of travel and any stop in Viry-Châtillon.
- A: The train goes from south to north south → north and goes via Viry-Châtillon
- E: The train does not go through Viry-Châtillon
- O: Train travels north to south and goes via Viry-Châtillon
In 2014 the following train names are in use. Not every train station to which a code letter has been assigned is actually a terminus.
| Destination | Name of the train journey (only scheduled journeys) |
|---|---|
| Gare du Nord | |
| Malesherbes | BUPE |
| Gare de Lyon | DACA, DICA, DOCA, DOPA, DOVA, DUPE |
| Saint-Denis | |
| Goussainville | FACA, FOLA, FOVA |
| Juvisy | JOPA |
| Evry - Courcouronnes | |
| Orry-la-Ville-Coye | LOVA |
| Châtelet - Les Halles | |
| Combs-la-Ville-Quincy | NACO |
| Corbeil-Essonnes | ROPO, ROVO, RUPE |
| Creil | SOLA, SOVA |
| La Ferté-Alais | TUPE |
| Stade de France - Saint-Denis | UACA, UOVA |
| Villiers-Le-Bel-Gonesse-Arnouville | VOVA, VUPE |
| Villeneuve-Saint-Georges | |
| Melun | ZACO, ZICO, ZOPO, ZUPE |
Planning for the future
A dedicated tunnel for the RER D line in Paris
At the moment, the RER B and RER D share the inner-city tunnel between the Châtelet - Les Halles and Gare du Nord stations , through which 28 trains (20 RER B and 8 RER D) pass every hour. The current system has reached the limit of its capabilities, which often leads to delays on both lines.
In 2011, the state and the region pointed out the absolutely necessary doubling of capacity. Expansion by 2025 is desired. Corresponding preliminary studies have already been commissioned.
If necessary, line D could then receive another branch in the north.
Connection clip RER B and RER D
It is planned north of Paris, a 11.4 km long diversion, the so-called. Barreau de Gonesse (connecting segment of Gonesse Arnouville RER D and Parc des Expositions - -) to between existing stations Villiers-le-Bel - Gonesse Villepinte line B to create a connection. Another stop is to be built in the municipality of Gonesse. This route is to be served every quarter of an hour by those RER D trains that are currently only going to Villiers-le-Bel. Construction is scheduled to start in 2017 and commissioning around 2020. The main objective with this construction measure is the residential areas in the eastern Val-d'Oise with the workplaces further east (e.g. in the Parc des Expositions exhibition center and Paris-Charles airport de Gaulle (CDG)) to better connect with each other.
Transitions to new modes of transport
- Since 2011 it has been possible to change to the T Zen 1 express bus line in the Lieusaint - Moissy RER and Corbeil-Essonnes RER stations.
- Since December 2013, the new Créteil-Pompadour station has offered a transition to the Trans-Val-de-Marne express bus routes and the RATP line_393 .
Further connections will be added in the next few years:
- From 2017 the Pierrefitte - Stains station will be the crossing station with the planned Tangentielle Nord .
- Also in 2017 is Gonesse - - Station Villiers-le-Bel Arnouville interchange station for train de TCSP Barreau Gonesse which with the station called Station Parc des Expositions line RER B will connect.
- The T Zen 4 express bus is also due to go into service in 2017 : no fewer than five transfer connections will be made between the Corbeil-Essonnes RER and Grigny-Center RER stations.
- In 2018, the extension of line 7 of the Paris tram to Juvisy station will be completed.
- The Tram Express Sud is expected to start operating in 2019 . You can change from or to the RER D in Evry-Center.
