If one time you had a chance to do an cab-ride in those EMU, JUST DO IT ! :D I worked on those machines, and their sisters called "Z5600" who can only work on DC part (south part) of the RER D (instead of the Z20500 which are AC/DC compatible). There 4 blocks of asynchronous motors per side edge, so there is 8 blocks of motors per EMU's. In french we call them "BM" for : Bloc Moteur which mean Motor block. If you want learn more about those fabulous RER, im here, feel free to ask me about.
Something told me that you loved the sound of the Z20500 ! ^-^. An awesome sound, the best of the RER and Transilien networks ! I worked on those machines, when i was a the SNCF, the maintenance center is not far from where you were at the first station, cold "Villeneuve triage".
I love this sound too, but when you're tired sometimes you don't want to hear this loud sound during all your trip, and you'd prefer something silent 😅
Euh no. sound of the class 319 looks like sound of the Z5300 and Z6400 at Paris (scrapped for the first, almost for the second.) Z5300 sound ruclips.net/video/CnyklU3FPwE/видео.html Z6400 sound ruclips.net/video/1mMULa5_JKY/видео.html
@@indra144The motors ? no! Mi79 use "EHO" motor from alstom , not GEC. But probably they use same control system with chopper and thyristors. In video ruclips.net/video/-KaEbL9Ec6A/видео.html we can heard the sound of the train and he is more close off the Z6400 series than Z20500 series.
I've always heard people saying 319's have a nice DC pulse sound to them but I've only had one and it sounded boring and didn't seem to have any sound to it, the only DC pulsing units I've had have been the earlier T68's (not T68A's as I only managed to get one of them and they sound different).
Are you sure you were sat in the motor coach? Only 1 carriage actually has motors which is the one with the pantograph on... 319s have a very distinctive 300hz switching frequency
I was just in Paris last week and we spent over €200 on tickets for that train system. Great design, so much better then what we have around Washington DC and way cheaper. And have you seen the metro train cars with large rubber wheels instead of solid metal trucks? Do you know what the design reasoning behind that is?
The train cars I'm talking about have rubber tires like you would find on a large truck riding on wide metal rails and guiding rails on each side to keep it on the track, and they do not operate at high speed. Like the cars in Paris metro line 11
It is DC not asynchronous AC. Ac motors (both asynchronous and synchronous) could not be used on trains until AC pulsing was invented, or more precisely, not until transistor technology advanced enough for transistors to switch large enough supplies at fast enough frequencies to replicate AC waves. You can not use an AC motor connected straight to the mains for such large loads or for loads with such variation in speed. Asynchronous AC motors are only efficient when the frequency is close to the motor speed. An AC motor will never have great acceleration as the starting up is always very inefficient as the motor is not moving and the frequency is 50 hz. As for synchronous AC motors, these are impossible to use until VF was invented. Also the incoming supply is single phase. So you can not run a motor of single phase as there is no rotating magnetic field. The largest single phase motor you can have is 3.1KW. The largest AC motor you can have where the motor pulls from a standing start at 50hz (in other words, no VF drive) is 20KW. So it is impossible that this train has an AC motor, and it obviously does not have a VF drive because of the sound and age of it.
As someone who has worked on these trains, I can confirm what +Ignacio Parra said, the Z 20500 use asynchronous AC motor. As a matter of fact they were one of the first train series in France who used them.
Beno Like any AC asynchronous motor. If the power source distributes AC current (25kV AC 50 Hz in France), upon entering the train it's transformed into DC current (1,5kV DC), then it's chopped via transistors or thyristors (it was possible since the 1970's for the transistors and 1990's for the thyristors) and ondulated as an AC current before entering the motors.
Can you go to Hamburg to review the DT4 train and it’s 3 series, one of which is a thyristor and has a lovely sound. The 2nd series dt4.3 to .4 has a GTO unique sound that I’ve never heard and the newest sets .5 and .6 use a normal Bombardier GTO drive. The thyristor drive is amazing however it is being phased out and trains are beginning to lose their hum at the start and just sound like the newer sets. I went there and it was amazing (U Bahn by the way)
cause the auto-sequential current source inverter can't modulate the current, only the frequency output for the asynchronous motors by doing some sub chopping at the start so you need a chopper to modulate the current and at the time thyristors were still a bit hard to drive especially at low angles so you can avoid that by lowering the frequency. hence the fact that it changes three times in a row.. to give the exact current needed for the inverters
It does have same AC pulsing. But actually the 20500 have a 3-step frequency that change (200/300/600 Hz) not like British Rail Class 319's 300 Hz with a loud 100 Hz hum. Z 20500 have same loud 100 Hz hum but in 25 kV, not in 1.5 kV.

What application uses you to measure the speed ??
This name is Z20500 :D I love take it
I was just in Paris last week and we spent over €200 on tickets for that train system. Great design, so much better then what we have around Washington DC and way cheaper.
And have you seen the metro train cars with large rubber wheels instead of solid metal trucks? Do you know what the design reasoning behind that is?
Well this is the reason why a DB Intercity Express train had a terrible accident in '98
Because it had some rubber on its wheels

I Forget I think that the reasoning is that the rubber tires are quieter and smoother
Could be... but if you have been on the 11 line you will know it's everything but quiet and smooth 😂
