6 Half-Metros that stop 2 out of 4 stations but you get on and off where you want!

in Brussels, the metros use the principle I was explaining and announce 40% energy recovery under braking

Uh and do you really believe in this cartoon? : Cheesy:

Rather find us real figures and technologies !! Like an altom or bomber datasheet ... and an encryption of what it costs on the network side!

Non-constant partial reinjection on a network is an unnamed electrical shit to manage ... it creates overvoltage and other phase shifts, impedance, reluctance and other electrical joyiness almost impossible to manage! SNCF does not really do it ... it's not for nothing!

Do not confuse the electromagnetic brake, widely used, and feedback, which is an "option" of the magnetic brake!
And it is easier to "brake in batteries" than by injecting into the network ...

So there is a gap between what is announced and reality! Sorry Raymond ... but that's how it is! It also surprised me when I learned this a few years ago ... so the reality is less green than a cartoon!

Take another example, this summer I did the Montenvers ... the rack railway of the Mer de Glace ...

Going down I was a little surprised to see electromagnetic elements on the roof ... I thought they were transformers * ... so I asked an employee !! What a denial! These are the dissipators of the electromagnetic brake! Why don't they inject on the network? The situation is ideal in their case: 20-25 minutes of constant descent!

If it does not inject it is certainly in this case for a security reason: constancy of the brake compared to the network voltage ... or quite simply because it is quite profitable to operate a centenary train almost in its juice! Yet if he has an activity that suffers from the melting of ice it is them! : Cheesy:

* they are transformers, they transform electricity into heat : Cheesy:

the techno of 20 or 30, or more for the sea of ice train, did not allow it easily : Mrgreen:

Have the physical laws of electricity changed in 20-30 years? : Mrgreen:

We can possibly understand the safety side for the Montenvers train ... for the others ??? : Cheesy:

not physics but the electronic power components and the servo to drive everything : Wink:

just as if you had the opportunity to repeat water injection tests it would be much easier to put electronics to optimize the operation than in 2001.

the only time I used this train it broke down

and we went down on foot : Mrgreen:

It was my first reaction, page 1.

Beyond the drawbacks already mentioned (waiting time on the platform before "his train" arrives), the concern is that on a metro line there are stations with very heavy passenger traffic (SNCF stations, interconnection stations between several lines) and others where there is very little passenger traffic.

But if you have never taken the metro at rush hour at "heavy traffic" stations, it is indeed possible to play the electric train by letting "half trains" pass, 2 or 3 in a row, in one of these stations. without stopping ..... It's just playing on the electric train, not transporting people .....

idea is not bad! It would unclutter the platforms with more fluid pedestrian traffic.

Sorry? You can explain?

Here is the animation of the concept (for those who still want to try to understand : Cheesy:
