Me in playing Train Sim World 5 💀

Great video very interesting i love that sound. i wonder if the new trains will make the same sound.

What station is this?

"Can you spot it yet?" no because the camera does not show the alignment in any form at all

Woah , Metropolitan is my favorite tube line

Memories of the 465/6s too

Memories of the 465/6s

Why are they tunnels at Finchley and forgnal station?

I wouldn't say fast, I would say normal speed!

why the f*ck does the train hum

The central line does this sometimes because its controlled by A.I and I know im commenting late but can you also go to sudbury Town to explore the village out there ?

in germany berlin the "S-Bahn" also sings but there its more of a choir sound but perfect sync

London is buggered! England id buggered!

You can find this sound in many countries. I heard it first on the Berlin S-Bahn.

I remember when I first rode on the Jubilee line for the first time when I was younger and when the train pulled in I was actually scared because I thought that there was something wrong with the train and I was like to my mum "why is the train making that noise" to which she replied "I dont know." I was especially convinced the train was faulty because I live on the northern line so I am used to the much quieter motors, and the fact the two lines using an identical design made me even more suspcicious.

Thanks for making this video , I needed to learn all these facts from you , Thank you s-o much and have a happy early christmas

70k Job.

Nice , I like that angle !

Central Line why did you do that 🤬

My husband grow up in london and adores the tube, he loves the 73 stock. He is just as angry with the fare evasion. I’ve both feel it’s the change in culture which has made this so much worse, people feel entitled. They don’t need to pay, this has made the funding issue worse. We need tube stock for the Bakerloo, Piccadilly, central lines even the jubilee and northern line trains are getting older now. We need to hire more revenue protection staff and improve laws so fare dodgers can be arrested and face a prison term for this. London is becoming lawless and it’s wrong

Jubilee Line: This Station is Baker Street change here For the Bakerloo, Circle, Hammersmith and City & Metropolitan Line This Train terminate at Stratford Nexts Stop is Baand Street please stand clear for doors 🚇

Sound like Melbourne train. 0:37

Sorry if Im to bother , but by any chance can you film a train at uxbridge , Please ???

I can’t tell if jubilee or Victoria line are the same speed or not 😅

There are videos which explain this to a better detail, I love the one by a Japanese railfan who has a working model of AC traction and you can both hear the sound and see the current...

The Victoria line is very Nice because of the sounds it make when it approaches a station , My favourite station on the victoria line is tied with Walthamstow central and Hightbury & Islington ! Have a good day

Awesome video my new friend!!

I really liked this deep dive on this one particular train class, though the volume difference between your narration and the plain clips was a bit extreme! I also highly rate Z&F Railways' video going through all the different types of technology, with excellent diagrams. But anyone watching this has probably already seen that one :)

Is that Northern or Jubilee

Some people call it Chopping? I don't get that?

It's just a noise

I keep hearing how an AC electric train system is more efficient than the DC systems, but I riding on Brisbane system I heard two clunk sounds every so often, I looked into it and discovered a disadvantage of the AC system, it is that different points of supply every few kilometers can have different phases and you don’t want the wires touching. Therefore magnets in the tracks activate a big mechanical switch that turn off the car’s electricy whilst it enters a dead zone and then another magnet turns the circuit on again. If you don’t want clunks in your journey, ride a trailer carriage. The Melbourne and Sydney systems running on DC don’t have this problem, I wonder how this is done in Europe’s AC systems and is it possible technically to have an AC train system to be in phase? Even if blocks are turned off when there is no train. I saw YT movies on starting a power station and the rigmarole required to manually sync the sine wave. Modern systems seem to do this automatically

In Melbourne, the Z3 class trams run on 600-750V DC and use a thyristor, called a chopper. I may not be accurate but I understand the instead of changing the voltage to speed up or slow the tram, a square wave is used and the width of the waves is what makes it go fast or slow, the advantage is that full voltage is used but the wave form has more or less square waves in it. I understand this method is used in wheelchairs and golf buggies and so on. The Z3 has a distinctive hum. I don’t hear it on the more modern articulated trams so I don’t know what they do, they still run on DC. I read they use an inverter and perhaps the traction motors are AC, I’ll try and research it. I know the inverters fail and the tram has to be towed in by the R10 truck. There might be a battery somewhere but not quite like the trams at Newcastle (NSW) which don’t have an overhead wire but charge supercaps at each stop.

As a visitor ilove that sounds and always thought it was on allubetrains.

Cool video 👍

At least it didn't overshoot

#VictoriaLine. #MyFavouriteTubeLine.

Fascinating......

If electric cars sounded like this then everyone would buy them 💀

The stepping sounds are caused by a multitap transformer. The high current DC supply is passed through a transformer on its way to the motors, as AC motors are generally high voltage, low current. To provide the ranges of power required for different speeds, the AC supply generated by the GTO is passed through different numbers of turns in a transformer, giving steps of output voltage. At each transition, the frequency of the AC switching needs to change back from a high frequency to a low one, before gently increasing again as the train speeds up. The reason the sounds happen as the train is slowing is that the motors are run as generators, and the power is passed back through the transformer and converted back into DC to go back into the power rail. This is called regenerative braking. It saves lots of power that would otherwise be lost as heat. Brake wear is also reduced.

I knew aolid state traction control systems differed but not the real reason. When SWR started the 707s when I couldn't se from the ovebridge, which train was coming in I often mistook them for the 700 Thameslink ones (Both being Siemens Desiro City units) and not the 455 or 300 series ones.

As an electrical engineer i never knew this, thanks for a fascinating video, gonna look out for this next time I'm in london

My favorite London underground line of all

i prefer 92 or 09 stock sounds, much of a violence symphony to me

Now here’s a crazy question for the train geeks and electrical engineers, why not just put alternating current down the rails In the first place?

The train stopped where instructed,then moved to allow passengers on a little further, perfect ,Where's the problem?

It sounds like a Gearbox

Some, not all, of the Class 465s on SouthEastern make the same sound, because they use the same technology.
