S train Full Power Unlocked 

these trains are totally awesome compared to the modern day trains

I was wondering why this video kept being reuploaded

AHA!

perfect!

Do you experience cursed videos a lot.

I see you are a man of culture

Go between King's Cross and Farringdon, also salone Square and Victoria etc

@@bb-3653 Why don’t they power up fast everywhere?

@@matthewsmith2787 no idea

Abhd

and south kenglisnton

I know right☺

It's a Bigger version of the 2009 stock, shame the 2009 stock isn't out doors or tried on another Line

On the upgraded sections the trains run at 40 mph in places. The tunnels are very old, and there are quite a lot of bends that limits the speed. Also I think they might be worried about vibration from too much speed. The Victorian tunnels may not have been designed for too much stress. We will have to wait and see how the system works once the upgrade is complete.

They are actually doing this on the eastern reaches of the District & H&C

it's very conjested though the central area, that will make the trains run much slower.

It took only 40 years but was worth the wait

Until the whole line goes ATO it will still be slow in the non upgraded sections

Yep

I work on DC third rail routes and its all about money and budget which is why improving power is a long and tricky process

@@court692able hmm I can imagine man, it would be cool to see the power improved and speed limits improve etc. It really does boil down to money doesent it. Let's hope something changes overtime. I think it probably will

With the Electrostars that run on 3rd rail, they can accelerate fast but it's down to the driver because I've been on a Class 376 train with the driver accelerating much faster than usual and slowing down a lot later just like a tube train.

I have actually been on the District and Hammersmith & City lines between West Ham and Barking, and I’ve used a GPS speed app to see how fast they are, and both have peaked at 48mph in between stations. I’ve noticed this more between Plaistow and Upton Park, and between Upton Park and East Ham. Between East Ham and Barking was 46mph, maybe due to track curvature in between. The 2009 stock is complete underground and therefore hard to get any signal coverage to record speeds. But the 1996 stock I’ve recorded speed of up to 56mph between Canning Town and West Ham.

@@projectr2451 yeah I use GPS too and I've noticed the same 46mph limit exactly where you spoke about. I need to go on the further path where they get faster. I think I've been on a jubilee line up to 60mph on the western side of its route between Wembley Park and another station.

The 117.5 meter train referred to in this video is the 7 carriage one.

Probably has higher gearing hence the slower sound

@@bb-3653 I would say the gearing is the same. It has the same VF drive. The speed which it changes from pulse cycle based PWM to pattern based PWM is the same (around 20 mph), and the speed where it switches to the second pattern is the same (around 30mph). If the gearing was different there would be noticeable differences.

@@benolifts hmm, it does sound a bit different to the 09 stock though, idk what it would be then. They are definately not the same exact in terms of audibility. The sound slightly different to me at least

@@bb-3653 The sound is made up of motor sound, VF sound, the sound of the train wheels, and the echo characteristics of the train and stations. The S trains is a bigger train with more powerful motors. The motors will sound difference. And the shape of the trains and station make the sound less intense as it is a larger space for the sound to dissipate. The VF sound is pretty much the same. Take a look at my video of the trains in Beijing in China. Some of the trains have Bombardier VF drives. Take a listen to the similarities and differences of completely different trains with the same VF drives. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Sj262-4Yjm0.html

The acceleration of Class 755 is much slower than the S, 2009 and 1992 trains. With national rail trains, the fastest accelerating trains are 379, 387, 395 and 800. which I estimate have a peak acceleration of around 2.5 mph/sec. All other national rail trains have disappointingly slow acceleration. If you compare UK trains to German S bahn systems, German trains accelerate much faster. The fastest accelerating S bahns I have been on are Cologne and Mannheim.

I think it's a software upgrade.

@@jwalker7567 Motors on the ATO lines certainly wear quicker, and need replacing more often

95 stocks have been running on full power since 2014

This level of pedanticness is why I don't associate with most train enthusiasts.

@@benolifts Nah I'm not trying to say it in a rude way but I'm just pointing out that every underground train us a stock rather than class or train.

@@OffTheRailsUK I would say that they are classes of train. They are all very different. I would say the naming convention of "stock" is just a tfl thing about what they call their trains. I wouldn't say that it is any different to a train class. Also some national rail train classes don't make sense. For example some different classes of train are almost identical but are given different classes, such as 375 and the original 377. Also some versions of class of train are completely different within a class number. For example class 377 contains both first and second generation electrostars. The two generations of electrostar are completely different and have few similarities. I would count these as different classes of train.

@@benolifts Yeah, same goes with the IETs, sure the 800s, 801s and 802s are different because one doesn't have diesel, but an 803 is exactly the same.

Hopefully

@@benolifts these trains are totally awesome compared to the modern day trains

Hey guys Austin is driving a S-Stock

Hey guys this is Austin

Hey guys this is Justin

Not really

@@benolifts well for me it dose. and thanks for replying to my comment :)

When I recorded it full power didn't happen between Sloan square and Victoria. Also it didn't happen beyond Temple. They are updating the route fast. Also not all parts of Seltrac have full voltage. Seltrac is an automation system and voltage is from a big square thing called a transformer. While they are upgrading two separate things at the same time, it doesn't automatically mean that both the seltrac and higher voltage will come available at the exact same moment.

@@benolifts uh

@@benolifts 2:55 SelTrac has been fitted along some of my country's train lines also & sadly some trains ended up crawling at 1km/h for 10s when stopping at platforms

Yes he pointed it out. But the s stock has a higher top speed

@@___-000 he said its the same rate. But seems slower because its larger.

I definitely think it’s slightly slower off the mark

@@matthewsmith2787 nah trust me , go on one between specific stations at night for example, they do absolutely well!!

you mean trains in general, no train today accelerates that fast and it’s unnecessary for tube stock as the distance between stations aren’t long at all

If it accelerated like that, people standing would fall over and people would be shunted to the ends of the carriage. People in transverse seating would be thrown sideways and people in backwards-facing seating would be thrown out of their seats. Not to mention how ridiculously large the motors and electrical supply equipment would have to be. Even the acceleration on an electric bus (not very aggressive compared to a car) is enough to push unknowing people in transverse seating. So there really is no need for such ridiculously fast acceleration (30mph/sec) and such fast acceleration (30mph/sec) comes with inherent safety concerns.
