How to take the RER from the Gare Du Nord to Gare De Lyon

If you want to opt to make the transfer between the Gare Du Nord and the Gare De Lyon by public transport, taking the RER train is the best option.

The positives are:

(i) It’s comparatively fast - it’s a two station hop on Ligne D (Sud), so you should be on the concourse at Gare De Lyon, within 25 mins of entering the RER station at the Gare Du Nord.

(ii) The line D platforms at the Gare Du Nord and Gare De Lyon stations have both been brightened up - and numerous staff can usually be found on the platforms at Gare Du Nord - so the station has lost much of what had been a somewhat intimidating atmosphere.
 

(ii) It’s cheap – a single central zone metro ticket can also be used on the RER.

(iii) It’s generally reliable, you won’t have to wait more than 10 minutes for a train and delays are very rare.


Not so great:
 

(i) The air-conditioning on the RER trains can be temperamental, so on a hot day, particularly if you are managing heavy luggage, it can be a tad uncomfortable

(iv) End-to-end the journey can be more confusing than you might imagine – hence the info below.
 

STEP BY STEP - From arriving by Eurostar at the Gare Du Nord to departing by TGV/Lyria from the Gare De Lyon.

1: The access from the Eurostar arrivals to the main concourse at Gare Du Nord is step-free - the exits from the voies (platforms/tracks) will be steps away from the front of the trains.

When you reach the concourse turn to the left.

What you won’t see anywhere at the Gare Du Nord are ‘this way to the Gare De Lyon’ signs.

The entrance to the RER station is towards the far left of the concourse (pictured below) - follow the signs pointing the way to RER lines B and D.

You’re looking for the escalators DOWN into the RER concourse

There are also (less visible) lifts down to the RER ticket hall – which you’ll see below you.

This image below has been taken from the top of the escalator.

When you reach the foot of the escalator, walk ahead of you into the RER station - the ticket machines and counters for the line D (and B) trains will then be over to the left - the access down to the trains is on the other side of the ticket machines.

2:  Buy a single journey central zone metro ticket - there aren’t any specific RER tickets for the central zone.

(Your end-to-end train journey tickets will NOT include the RER).

Either use the machines (there are large numbers of them and they have good English translation), or use the staffed ticket counter - but these can be closed in the afternoon/evenings).

Though there are so many ticket machines available that the queues for the ticket counters can be comparatively short.

3: From the RER concourse follow the signs for ‘Ligne D (Sud)’ - the green sign pictured below,  ALL of the Line D trains heading in this direction will call at Gare De Lyon.

It’s important to use the ‘Ligne D (Sud)’ ticket gates - as there are separate/different ticket barriers for trains heading in the opposite direction (Nord).

If you have luggage, use the lift on the other side of the ticket gates - there are only stairs and no escalators DOWN to the platform.

4:  When you have descended to the platform that's shared by Line B (Sud) and Line D (Sud) trains – the line B trains use the track towards the wall, while the line D trains use the track towards the middle – facing the northbound trains.

All Line D trains heading south from the Sud platform will call at the Gare De Lyon - which is two station calls from Gare Du Nord, so don't worry about the final destination of the train.

Check the electronic departure screens on the voie/platform to double check that you will be boarding a Line D train - or confirm it with the SNCF staff that are usually on the platform.
 

5: The train will be double deck, but don’t bother with finding a seat.


It’s easier to wait by the doors as the travel time is only around 7–8 mins, though allow room for people to alight and board at the intermediate station, Châtelet – Les Halles.

6:  At Gare De Lyon there are escalators (and hidden lifts) up to the level above (level -2) that houses the exits from the RER.
You don’t need to use ticket barriers to exit the RER.


7: When you have exited the RER station look for the ‘electronic departure indicators (TV screens) that are marked ‘Grande Lignes' – only these indicators list the long distance departures.

8: Follow the signs to the 'Grande Lignes' trains.

and you will be in Departure Hall 3 - the sign above is somewhat confusing as you need to pass through Hall 3 in order to access Hall 2.

Hall 3 is pictured below.


Look for the blue departure screens.

The specific platform/track/voie that a TGV/Lyria train will be departing from isn’t usually confirmed until around 10-20 mins prior to departure.

Voies/platforms/tracks A - N are above Hall 3 - and those that the long distance trains tend to depart from, have escalator access.

Voies/platforms/tracks 5 - 23 are in Hall 2 - which is at the far end of Hall 3, a slope and an escalator ascend up into Hall 2.

As will be seen above, prior to the specific platform/track/voie being confirmed, you will be instructed to wait for your train in Hall 2 or Hall 3 - Hall 3 has a dedicated waiting area - at the far end, over to the right.
 

9: However, you don't have to wait in Hall 3 -  if you have more than 45 mins to wait for a train, then an option is to make your way to Departure Hall 1 and wait for your train there.

If your train is leaving from Hall 2, the easiest option is to wait there until the specific voie (platform/track) has been confirmed - Hall 2 is pictured below.

Hall 2 is usually very busy, it's not big enough to cope with the number of trains which use it.

Try to find a quiet spot from where you can keep an eye on the departure screens, the voie (platform/track) that your train will be leaving from won't be announced.

If you don't have luggage, so won't need to make use of the limited luggage space on the TGV trains, hang back and avoid the inevitable stampede towards the train - your seat(s) will be reserved, so you don't have to rush to claim it.
