S7Tube Stock train |FAST Acceleration+beautiful traction/drive sounds✨️☺️(near max speed)

[@745ga]

It's about time yoh recorded these trains, you should go on the metropolitan line i think the line can go like 60mph

[@gapthemind--mindthegap8524]

They can, but they dont hit that speed often times and dont do it anywhere near as fast, their upper acceleration rate is capped near and after baker street mostly. They struggle alot because it seems the power supply hasnt been modified to allow them to hit max acceleration capacity. In that reigion, which is silly if you ask me. They need to ne getting to upgrading that ASAP.😂

@@gapthemind--mindthegap8524 I'm not sure but I think it has something to do with the fact that part of the Metropolitan line has shared tracks with the Chiltern Railway.

@@Matty12333 i guess they should improve that. Means the s8 stocks can blitz it up to 60 in a heart beat.

[@LucasTheElectrostar]

As I've had a cab ride on one of these, I have to say, these are very fast to accelerate. Even when the driver is driving it manually, the acceleration is still very good.

[@gapthemind--mindthegap8524]

Trust me man they are rapid

[@TransportEnthusiast81]

I've been wanting to see what the actual fastest the District Line has travelled. I've seen these went over 50 then stopped at 52mph and on another ride to Upminister the fan pitch was higher than the speed it actually hit over 50 i thought it was gonna be 58mph like the Jubilee line I seen one hit 59mph Underground and it was very faster than usual. These have better acceleration in ATO, maybe in the future they might increase the speed limits probably to 58 or something. Thank you for showing the results.

[@gapthemind--mindthegap8524]

@@TransportEnthusiast81 it makes no sense how they are geared for 62mph but with the amount of technology that exists, they somehow cant hit those speeds. I personally think stuff should be dont to improve the speed theres tech that limits the trains from over speeding, and the acceleration is fast enough to hit 62mph. Also have you traveled in a cab ride before? Also i listen to the motor/fan noise too. It usually indicates if the motor is at a higher speed rpm. And depends on the trai what speed that can indicate.

one thing i hate is the brakes since they are SO HORRIBLY LOUD GET SOME WD 40 ON THOSE WHEELS

[@gapthemind--mindthegap8524]

@@Westlondontransportguy7045 agreed , i think it's because tread brakes/calliper brakes aren't as needed for main braking and are probably less required for lubricant. I could be wrong , their only really used at lower speeds before stopping, or halting the train entirely.

[@Matty12333]

Seems a lot faster now, it used to be around 40 mph top speed before ATO

These trains were manufactured in Derby if it was manufactured by bombardier.

Indeed. They were. Back in the late 2000s..

From 2008 to 2017

[@SolomonClarkeTrains-nw1sf]

0:10 it got 33 seconds to 50mph and 43 seconds to 55mph. Still slower than a 1995 stock which takes 29-30 seconds to 50mph

[@gapthemind--mindthegap8524]

It was slightly uphill tbh. But its probably slower by a bit

[@Matty12333]

2009 stocks are faster

[@SolomonClarkeTrains-nw1sf]

@@Matty12333 Yep, I've heard that

[@gapthemind--mindthegap8524]

@@Matty12333 many reasons for this. 09 stock is lighter, and as a result the power to weight ratio is better. S stocks probably have a relitively lower power to weight ratio, but utilise a surplus of motors. More motors means that power can be given to the motors faster as they are distributed among multiple motors and thus it can take of faster at lower speeds without overloading the motors. However it gets to a point where lower speed acceleration tapers off and the train takes up its max power and continuous acceleration takes over. The continuous acceleration is drawn back a bit because the S stock likely has relitively less power output than a 95 stock. Roughly translated. If the S stock was a smaller train like the 95 stock, it would use less max power than a 95 stock. Another factor could be software limits meaning it tapers off its power as per the programming as it hits higher speeds. For the power that they use, the S stocks are pretty good. Its also likely that the 09 stock doesent hit 50mph as fast as the S stock, but at lower speed acceleration is just better so it gives off the illusion that its faster to max speed than the S stock when it might not be. So far 95 stocks are recorded to be the quickest.

[@gapthemind--mindthegap8524]

The S stock accelerated like a 376 after 45mph.

[@Matty12333]

62 mph is the speed they should be reaching

[@gapthemind--mindthegap8524]

Weather and line speed may not enable that. Who knows if it can hit that or not. We will have to see another time😊

[@Matty12333]

1996 stocks are faster

[@gapthemind--mindthegap8524]

They have the same max speed. And these are faster unfortunately. They have much better acceleration..however thr 1995 stock is much faster than both of these trains

[@Matty12333]

@@gapthemind--mindthegap8524 1995 stock has an advantage it has 4 carriages motored out of 6. 1996 stock has 4 out of 7 motored. Although despite this the performance isn't too far behind the 95 stocks

[@gapthemind--mindthegap8524]

@@Matty12333 id beg to disagree with the 95 vs 96 stock. Its true that The 95 stocks motors enable it to accelerate much better than the 96 stock due having 8 motored bogies with 6 carriages compared to 8 motored bogies with 7 carriages. However theres a decent margin for acceleration. Removing 20 tons of carriage will enable this. 95 stocks actually beats the S stock to 50mph despite the S stock having all wheels motored and better starting acceleration. The 8 motor bogies of the 95 stock enables much better continuous speed than practically all tubes except the 09 stock , which i have no idea how fast it is. 96 stock has good continuous acceleration for what it has. But the advantage of 95 stock is substantial overall. One thing ive noticed is that the 95 stock having less carriage to motor ratio means that is can have better protection against wear and tare as the motors have power distributed across 8 motors with 6 carriages instead of bearing excess weight and power. Its likely why 96 stocks tend to have weird motor anomalies from time to time. I could be wrong about the wear and tear theory but yeah.

[@Westlondontransportguy7045]

that and the sub surface line are using the same signalling system
