What is the operating and average speed of RER trains?

I don't know the average speed of the RER but I could give you the max speed by lines and rolling stock.

RER A: 120km/h
MS61: 100 km/h
MI84: 140km/h
MI2N Altéo: 120km/h

RER B: 120km/h
MI79: 140km/h
MI84: 140km/h

RER C: 140km/h (This line is extremly slow in the central section, only 40km/h as max speed)
Z5600: 140km/h
Z8800: 140km/h
Z20500: 140km/h
Z20900: 140km/h

RER D: 140km/h
Z5600: 140km/h
Z20500: 140 km/h

RER E: 140km/h
MI2N Éole or Z22500: 140km/h

Don't forget that it is only the max speed, not the average speed.
RER lines are very complicated that the average speed may vary depending the service.

Well, it'd only be a matter of calculating the total travel time it takes from one end to another. I bet there are some schedules on-line that you can use. That should give you a pretty good estimate.

But I would need to know the length of the services.
I only have the length of the whole line and a RER line has several branches.
It is impossible that a train runs through the entire line.

That was nicely put. So it's safe to assume that RER generally runs at 140 km/hr (especially outside the urban core).

But I was wondering how they manage to run trains with quite varying top speeds in Line A. Suppose an MS61 train is running at 100 km/hr in RER A, then an MI84 train running behind it cannot run at 140 km/hr because there has to be a constant gap between 2 services and there is no scope of overtaking.

That's what I thought. It will be difficult to find the length of individual branches. But I guess there is no branch in RER E? How much does it take from end to end to cover 52 odd km in this line?

I would not assume this.
Even outside the central part, there is a lot of different speed limits.

The max speed on the RER A is 120km/h, so even if a MI84 can run at 140km/h it doesn't go faster than 120km/h.
Rolling stocks are quite segregated outside the central part, MS61 only serve the Boissy and Saint Germain branches while the MI84 and MI2N mostly run on the Cergy Poissy and Marne la Vallée branches

There are two branches on the east of the RER E.

Then calculate the time between the terminus of the branch and the point where it joins the main line or another branch. Simple as that

But you shouldn't forget that there are local, semi express, express services.
By exemple a train going in Tournan don't stop in every stations.
And what could seem easy for the RER E is not for the RER C.

Yes, calculating the average operating speed probably is going to be more difficult than you'd think. I also believe that you should factor in the number of people traveling on a train or line at any given time. Trains usually operate on lower average speeds during peak hours, as dwelling times at stations increase. That does affect a far greater number of people though than during day time or late evening service.

I watched a special (National Geographic or Discover Channel I think) about that horrible train crash. I was saddened by the story very much.

I have to say I was at Gare du Nord two weeks ago... And it was completly trashy... It was the worst train station I´ve never been... It was absolubly bad indicated and so labyrinthine I hope they renew it as they are doing with Gare Saint Lazare and Les Halles



My heart beats for Paris

Oh no! I'm sorry to hear that you had that experience. I went to Gare du Nord in March 2009 and although it can definitely use an upgrade, it was not that bad in appearance, at least from what I saw.

Did you take a train there? Or just saw the station?
