Also in a city like Paris (and indeed London) where interchange between lines is so easy there is no need to have multiple destinations on the one line. It is far easier and better to run the separate and allow people easy interchange.

Neat photos. And that station looks pretty decent compared to the other phantom stations that have been riddled with graffitti.

I sometimes visualize how Haxo would look if the sublines were indeed merged. I also wonder where they would place the access points into the station should it be opened to passengers.

I was reading on the Paris Metro website that the Porte d'Orleans station on Line 4 is being renovated to modernize the station, add an additional access point, and prepare the station for the extension to Mairie de Montrouge. I think that this is very good.

Minato, have you heard anything regarding the MP89 and Line 4?

That requires a little theory.

As soon as you start running different services over the same tracks, there are some significant disadvantages to be dealt with:
  • Train frequencies (tph) on both services will have to be synchronised. This means less flexibility in tph per service, and consequently, frequencies cannot be so easily adapted to transportation needs for that specific service. Practically, certain branch lines will have to offer more - or, worse, less - trains than would actually be required;
  • Delays on one service can lead to delays on the other service, because they are run interdependently;
  • The maximum frequency on branch lines is restricted, because the service running on the branch line has to share its tracks with (an)other service(s) on the main line.

As ajw373 said, this leads to a service mess on the London subsurface lines. New York is a similar example; this network has an even higher extent of interlaced services.

Of course, there's also something to gain with this type of network setup:
  • More one-seat-rides for individual passengers, as different services serve the same platform. Individual riders can take a direct service to their destination, so there's less need to transfer;
  • More flexibility in re-arranging services, which can come in handy if certain stretches of the network are out of service for maintenance work;
  • If less service is needed on branch lines, adding branches to main lines can be a cheaper alternative to building a completely new main line.

The 13 line is like that though.

Also the RER network also functions this way.

Got it. Thanks!

Now I can see why some lines in New York can be a mess, the track that carries Lines 4, 5, 6 can be attested to this I guess.

What is the current status of the rolling stock? The MP 89 (Line 4) & the MF 01 (Line 5)?

That Paris Metro is one of the best subway systems I've used. Guangzhou is pretty impressive as well.

"Desolate"? I see a lot of people in that picture...

(or does "desolate" mean something else in English? Hm...)
