Is the RER a subway system or is it an above-ground tram?

My VRBO apartment is near the Luxembourg Garden RER stop. I will arriving at Gare Du Nord from Amsterdam, it looks like it is a straight shot with no transfers on the blue line to Luxembourg.

Also it looks like it is a straight shot from Luxembourg to CDG.

Am I reading this correctly? It almost seems too easy, LOL.

I've used the RER very little, but it does take you above and below ground.

There is a transfer in Gare du Nord even though it is on the Blue Line. You will have to get off the train and go up one level and catch the continuation of the Blue to CDG. The maps do not make this clear and the only way you know is if you pay attention to the announcement on the train.

The RER (and the Métro, for that matter) is mostly below ground within the city and mostly above ground outside.

I assume you will arrive at Gare du Nord on the Thalys at street level. You will go down into the RER at the east end of the station. At Luxembourg, there are escalators to take you up to street level again.

It looks easy because it <u>is</u>.

I'm not sure what Franto is referring to, maybe there was a special situation when Franto took the RER to CDG. When I rode the RER, it was indeed a straight shot from CDG to the Luxembourg stop and back, no transfers necessary. Just make sure you get on the right train; they don't all go to CDG as the line splits before it gets there and some trains go to Mitry-Claye instead.

You only have to transfer on that line when there is a metro strike going on. So the short answer is, it a straight shot from Lux to CDG.

One more confirmation - RER from Denfert Rochereau to CDG: no transfer necessary

Hi vivi,

The RER is a train system that supplements the Metro by going out to the suburbs.

Sometimes it is above, and sometimes it is below ground.

You have a good location.
