great pictures man they have to clean up the rail cars.

anyways a question i wonder is Rubber Tires metro better or is steel Rail better for the metro because some lines have tires and some others is more traditional.

and which is cheaper Rubber Tired or Traditional Steel Rail?

Rubber tired are more efficient for low interstation due at the fast acceleration and fast breaking.
Steel rail is far cheaper and more efficient in overground part.
Honestly I don't see any big difference, the difference was in the 1950's 1960's but not now anymore.

According my mesure with the very little part installated, the height of these PSD is about 170 cm.
I mesured it with my height and PSD are a bit taller than me.

I'd like the color of line M1 (yellow) to be used (for example) on the doors, or something like that...

Infact only three least busy lines () don't have automatic system, so 13 lines have but *only the line 14 is driverless.
After the , according the rumors the lines could become driverless.

* I exclude the three airport lines.

As far as I know, rubber-tired trains were put to decrease the harmful effect of the metro on historical buildings in the center of Paris, where it is almost totally underground. Rubber-tired trains do not produce so much vibration and don't endanger the foundation of the Louvre, for instance.

I don't think that it is the main reason.
The line 3 that run under the Sentier one of oldest district of Paris is not rubber tired.

No. The main ideas are reduced track maintenance, and higher acceleration/braking possibilities, also less noise.

Vibrations are not that harmfull because those trains are really lightweight.

Really? I've been to a downstairs seating area in Newcastle cafe, the metro trains run underneath and you can feel the vibrating of every passing train. The Tyne & Wear Metro is also deep level, which the Paris Metro isn't, and also uses light rail technology, which Paris also doesn't, so I think you're wrong.

I do not really think maintenance is cheaper, and it doesn't have much in common with acceleration which depends mostly on the power and the torque of the engine.
I've been to Paris several times and I wouldn't confirm definitely that rubber trains are less noisy. Moreover, ordinary trains in many other countries (Belgium, China) seem to produce really less noise.

No, Grygry is right rubber tired trains have higher acceleration/braking possibilities, in a subway network where the interstations are small it is a very big issue.
That's also why most lines had automatic system since the 70's.
In an other way modern steel tired trains like the MF2000 have similar possibilities as a rubber tired train but it was not the case in the 1950's 60's.
