The 1995 stock has a higher ride height than he 1996 stock because it uses air suspension whereas the 1996 has spring suspension.
In fact it rides so high that they had clearance issues on the bank branch and had to do some work on the tunnels before they could enter service.
1995 also has flexframe bogies where the bogie is split diagonally and joined by rubber. This was because they were worried about cracks developing owing to the terrible track on the Northern Line.
Oh, that's interesting!
LMAO XD
Challenge: This type of video, but for the Class 507 and Class 508.
Ooh, now we're talking 😂
@@NickBadley if you did do that, you've got to talk about how the 508s used to have 4 cars, but one of them was taken out to lengthen the 455s, which now have an odd car (from the 508s) that's different to all the others! I'm not sure how that would fit within the video, but it's the sort of information we'd love to see!
Another challenge would be differences between class 45 and 46 Peaks (and there is at least one visual difference)
they were different i think but one of the stocks got refurbished to look more like the other one so they look the same
@@NickBadley fact: due to the DC compressor pressure being different on the 507 than the 508 the 507 lights flicker in tunnels where as 508 don’t. (I haven’t seen a 507 flicker since 2020 though on Moorfields but on the Wirral line I have)
Extra information about the first differences:
1995 stock is using IGBT-VVVF made by Alstom, while the 1996 stock is using GTO Thyristor-VVVF also made by Alstom.
A shame it was missed out of #1, as this is a key technical difference.
GTO is the older technology too, having been around since the early 90s.
IGBTs have been used for many years since!
I feel that the 1996 and 1995 stock sound similar when coasting but sound very different when accelerating or braking.
@@PeteS_1994 Makes sense. Similar/same motors but different electronics.
@@bfapple Why does the 1996 stock have older technology (GTO) than the 1995 stock (OniX)?
production delays?
The 1995 stock has Selective Door Opening to cope with stations with short platforms, as the 1996 stock was built to a cheaper spec, it lacks this feature
Interesting that there's so many differences, given their overlapping construction and almost identical specs! It's almost like they're doing an A/B test on things to determine the final standards for later stock.
Not quite. It’s because the Jubilee spec was frozen earlier in the decade.
can't beat the 1996 sound!!! can't believe my brain picked up on the different sounds without me noticing, guess that is why i always preferred jubilee route videos!
Brilliant video Nick, there are differences I never knew about until now. I deffo say that the 1996 tube stock is my favourite out of the 2 because of the awesome motor sounds. :)
Same here, honestly! I love the noise they make when they leave
I love the 1995 stock ss it has the oh the prettiest screeching noise and the height suspension and the fact it is more modern than 1996 stock despite the confusing names
Not really the motor sound. They use similar motors, but different variable frequency drives (module controlling speed of motor). 1996 stock uses the more primitive GTO-VVVF system (which has a lower pulse frequency, hence more audible), and the 1995 stock uses a more modern IGBT-VVVF system (higher, less audible pulse frequency). They both use induction motors.
The jubilee line will always be music to my ears
Very interesting video I learned new things... Always knew the obvious sound differences they had when trains are moving, pulling off and stopping but never noticed the different sounds the doors make when opening with one being higher pitched than the other! Never knew many other things pointed out in this video as well like the information screen differences... Very informative 👍🏽
Actually, I'd say the door alarm pitches are lower on the 95 stock, since the 2015 refurbishment actually reduces their pitch and the original was kept for the 96 stock.
The 96 stock also used to have 6 coaches until around 2005.
Yeah, I’m glad that the 96 stock chime pitches haven’t been changed, not a fan of the lower pitch ones ok the 95. Sounds torrid
Who have known that about the carriages.
@@gapthemind--mindthegap8524 Literally anyone who lives in London
@@OffTheRailsUK nah most people aren't that perceptive. Alot of us were kids too when this happened, I'm 24 snd thought they always had 7 carriages
Great video Nick! I've travelled on both sets lots of times. Thank you for sharing the differences, I've learnt lots more of them🙂
Glad you liked it!
brilliant video lots of interesting facts that i hadent noticed but i know that the 1996 had yellow poles before they were refurbished but i do love the sound of the 1996 stock when leaving the station and i like the doors opening sound on the 1995 stock
Thank you for a very informative video Nick. I just came across it and thought it was well worth a look.
Amazing video! I’ve noticed most of these consciously and the rest of them I’ve noticed something was off/different on the 96 stocks (I use the 95s a lot) but never quite been able to quite work out what.
The 1995 stock feels like a Piccadilly line train and the 1996 stock feels like a futuristic white tube train
Great video. ☺️ Both trains use the same motors but they have different traction inverters which is why they sound different when moving off and slowing down to a stop but sound the same at speed.
Great video! Another difference is on the front access door. The 1995 Stock has a traditional hinged door with an external handle, whereas the 1996 stock has a door that fold outs with a built in emergency evacuation staircase. The door does also open inwards in the normal way too but doesn’t have an external handle.
Nice one Nick. As a fellow train nerd I love this type of video
i never actually noticed the doors being slightly different in colour so i’m glad i learned something new.
I have enjoyed all of your videos, that I have watched since I started following you. I live on the other side of the Atlantic, so I enjoy seeing different bits of Britain.😊
Glad you enjoy!
great video, just found your channel- I'm always in favour of more jago Hazzard-style content. looking forward to more!
Great video 👍
I must admit there are a few differences I hadn't noticed before
Very informative video! It seems like the 1995 and 1996 stocks share the same car body, but are mechanically and electrically very different. This is comparable to the difference between the R143 and R160 cars in the NYC subway system.
Thank you very much for this video I learned quite a lot of things.
Nice comparison- I’d not noticed some of those! Great video
Another great video. Really glad I found your videos through mersyrail. Keep it up
Thank you very much! :)
Very nerdy stuff, I like it! I've just found your channel by the way. Hope this channel continues to grow.
Do you or anyone know why the grab poles on the 1995 Stock isn't black? Given that all the other deep level tube stock have grab poles in the same colour as the line on the tube map, I would've thought that it'd be logical to make the grab poles black to reflect the Northern Line.
It is because of visually impaired people may have trouble with black, whereas they have no trouble with yellow.
Interesting there some I didn't knew about, great video Nick
Lots of very good 👍 facts that I didn’t know except for the sound of them!
I really liked the buttons including the original ones on the district lines when they first came out. Would be nice to have some kind of a fidget gadget with the buttons including lights. Enjoyed the video Nick and will add it to my playlist.
Another thing, the refurbished '96 stocks have yellow and black triangles on the edges of the doors but the '95s don't
Amazing video, plus the two tone on the Jubilee Line actually used to be the same as the Northern although maybe around 2016 they were lower pitched.
I believe so, yeah
Some of these are so Nerdy 😂
I like it! What a great video!
The fact that I've wanted to know this for as long as i can remember.
The Jubilee Line cars were refurbished a few years ago, and the Northern Line some time before. They must have taken some insights from that refurbishment and applied them to the Jubilee Line. Also the moquette of the Jubilee was first used in the Bakerloo Line refurb of 2016.
In the Jubilee Line driver’s cab one could still see the very original moquette, purple and turquoise. Even before the refurb, the passenger seats had a blue cover, which was a total mismatch with the rest of the interior with its yellow and turquoise accents (typical 90s). I guess the original covers didn’t last very long for some reason
The 1996 stock used to have grey interiors, they changed them in around 2017 that’s when the silver grab poles came in.
Fun fact: 2 brand new 7 car jubilee line trains were introduced in 2005, they also added the 7th carriage to rest of the fleet. The 7th carriage is the 4th or 5th car depending on direction of travel. You know your on a new train or carriage because the passenger information dot matrix is orange instead of red, to comply with newer regulations.
Another subtle difference that would otherwise go unrecognised is that the headlights of the 96 stock are more of a cooler whiteish tone whereas on the 95 they are a warmer yellowy tone
That was very interesting! I don't understand why the traction motors sound ever so different though as they're only one year apart in year of construction. Got to love that 1996 stock traction motor sound! ❤
I’m not sure if the motors are actually different. It’s the three-phase inverters that result in the sound as a by-product.
It's because TFL were using relatively new 1983 stock on the jubilee line but their single doors were proving impractical due to high capacity. This meant TFL needed a large number of trains quickly. The compromises made with the 1996 stock (there are several btw including spring suspension instead of air suspension) were to reduce costs and decrease manufacturing time. GTO transitiors were well established so were easy to get hold of, hence why they used the "older" (but cooler imo) technology. IGBT transistors were brand new, revoloutionary technology and so were expensive and hard to get hold of.
The GTO transistors have a very different way of handling changes is speeds as the have completely different limitations to them.
The older GTO Thyristors cannot handle the same high frequencies as the newer IGBT. This is important as the frequency needs to be increased in order to speed up the motors. As a result, they have to change the PWM pulsing pattern in order to reduce the switching frequency. It's this pattern changing that causes the distinctive sound when accelerating / decelerating.

I copied my reply from another comment lol bcs i cba to write it again haha
Great video! I'd like to add some curiosities:
1. Before refurbishment, the handles of both 1995 and 1996 Stock were yellow;
2. The panels besides the doors are shaped differently on the two types of trains, and before refurbishment, on 1996 Stock cars they were aquamarine in colour, as the panels below the lights;
3. Until 2005, 1996 Stock trains were made of 6 cars too; interestingly, the LED display of the added seventh car is amber instead of red, and its floor was black instead of grey.
I enjoyed it and learned so much
The front cab doors are also different and the plastic casing by the doors. The way the carriage number is displayed in the train as well.
Good job! Can you make video with 10 differences between 1972 and 1973 stocks?
96 stock trains were originally 6 car but were lengthened several years after entering service. They do not need SDO as all stations have platforms long enough for the full train. Had the use of 9car trains not been abandoned in WW2 the Northern line would have had noticeably longer trains than it does today.
As I am tone deaf the door opening chimes sound the same to me!
Great video mate
Why do Jubilee line trains sound like race cars when departing or arriving?
Another thing with the 1995 stock is that the close door beeping stays beeping when the doors are closed and on the 96 stock the beeping stops when they close
Ooh! I actually never noticed that! Good catch!
This has been most interesting thumbs up from me 👍🏾
Excellent video
I’ll always prefer the 1996 Stock more because they’re a lot more fun to ride, especially between Green Park and Canning Town and that I like certainly like white and grey more than black
One question. Technically, could the 1995 stock be used on the jubilee line?
Great video
i enjoyed that, you should do differences between class 377 and 375
On the northern line the grab poles used to be yellow like the S stock but a little lighter
Do they both operate on the same routes?
Which acceleartion sound do people reading these comments prefer?
0:34 Imagine this sound on a Tesla🤤
The 1996 stock arriving and departing sound is similar to the Class 465/466 Arriving and Departing sound.
That’s some useful information they
A long time ago [before ATO], when the driver would release the doors, the two tone sound would play even though the doors weren't open to alert the passengers that they can now open the door. So basically it's the door release chime.
The Central Line stock had these open buttons too, and worked a similar way. But of course, nowadays they are completely bypassed, and rendered useless, which explains why the 1995 stock had the buttons replaced with a single indicator after refurbishment.
The 1996 Stock does have a few orange led displays (I think they might have been the extra carriage when the 96 stock was upgraded to 7 cars
One question I had in mind, are they couple-compatible with each other?
Can you do the 1972 and 73 stock
Nice video 😊
Before refurb, the 96 stock had turqoise panels.
Also long ago I think the 96 stock LED signs "flashed" text instead of scrolling
The sound difference is because the 1996 stock uses older technology than the 1995 stock. It's because the 1996 stock were ordered first, but due to delays they were delivered last. In the time between the two orders, Alstom were able to offer updated IGBT technology instead of the GTO Thyristors that were locked into the 1996 order.
I thought the first 96 stock ran before the first 95 stock?
Question: Would that mean that the Northern Line was supposed to have that "Jubilee Line Sound"?
@@ikec-pw5sb probably
@@ikec-pw5sb no, the northern line doesn't have that sound because it has the newer IGBT technology.
The older GTO transistors (the ones the 1996 stock have) have a very different way of handling changes is speeds as the have completely different limitations to them.
The older GTO Thyristors cannot handle the same high frequencies as the newer IGBT which are needed when speeding up. As a result, they have to change the PWM pulsing pattern in order to reduce the switching frequency. It's this pattern changing that causes the distinctive sound when accelerating / decelerating.

Can't remember if I commented before so if I have please forgive me. The 95 stock has a more 'modern' traction, suspension and TMS system. The 96 was specified cheaper as the stock was bought in by LUL. The 95 Stock is under the PPP scheme and are owned and maintained by Alsthom. The 95 Has better: Traction packages (motors etc, hence the sound difference), Better suspension (they have air ride as there 96 just has springs) and the TMS (Train Management System ) is better positioned for driver convenience.
Other quirks are the escape ladders in the drivers cab. The 95 stock is much slimmer and compact but much more fiddly to setup and pack away, TMS programming is slightly different for the displays and the audio too. Oh we now have better in cab monitors.
Yeah 1996TS has the louder noise of the door opening and closing and the interior inside is different
One basic difference to spot out, it’s the jubilee line map on the 1996 stock and the northern line map on the 1995 stock
Nice video
You should make a video comparing the Metro Cammell class 465s and the BREL/ABB class 465s
What about the unrefurbished 1996 stock vs the refurbished 1996 stock?
Another challange 10 differences between the Class 801 and Class 800
Another difference, their announcements are different. Whilst both being mainly voiced by celia drummond, her style on the jubilee is very different compared to the northern which I find interesting
A slight correction on point 6, the new trains plus the new carriages (originally the 1996 stock were only 6 carriages long) have orange on black DMIs instead of red on black
I just only noticed if there is a button next to the door to Identify whether it is 1995 or 1996 stock
Despite the names, the 1995 stock is newer and came into service later than the 1996 stock. The sound difference comes from the 1995 having more modern control electronics that can switch faster, so you hear a higher pitch.
1995: “This station is x, this is a northern line train terminating at y”
1996: “This is x, this train terminates at y”
you should do this on the piccadilly and bakerloo line stock
2:28 Before they were refurbed, yellow hand rails and a sorta gross green colour surrounding the dotmatrix display :)
Also the interior cartridge number sigm is diff (above the in-between doors
I just find it interesting that despite being numbered later in terms of year, the 1996 stock is actually stuck technologically in 1991 when compared to the 1995 stock being more advanced.
That’s interesting, do you have more info on that? (Being technologically 1991)
The 1996 uses GTO traction similar to the Networkers and the 323, which is why it has its certain sound, and the 1995 stock uses IGBT traction with Alstom's ONYX Drive, which is the shrill, continuous whine.
@@yy17782A lot of the contractual design detail was frozen in 1991.
@@thebcplayer Singapore's C751A rolling stock meanwhile use ONIX IGBT but sound like a higher pitched version of GTO instead, though the C830 that uses the same IGBT tech sounds more the '95 stock. Might be due to differences in the voltages used (1.5kV & 750V DC respectively)
@@lzh4950 Line voltage and motor voltage don't always exactly "line" up, pardon the pun. Multivoltage trains are a great example of this, that may use 750V third-rail power usually, but can transform the 1500V OLE voltage down to 750V for pantograph operation.
also, for some reason, when I am on the northen line, I hear this strange sound that sounds like a hair dryer, I hear it most before the train departs a station
Love this video Nick! How about a difference between Class 317 and Class 455? Even though the most obvious is one being AC overhead 25kv and the other DC Third rail power, but both look almost identical
Yeah I even know some
455s, 75mph use EE507 motors (ancient motors) using a lack of power
317.
100mph, use GEC motors G315bz motors etc etc
How about a video on the differences between the Flying Scotsman and the S7 Stock?
I learnt 3, 4 but i knew the rest, still a good video
Excellent video!! There are a lot of differences that a lot of regular passengers would not even notice.
Positioning of the door buttons are different too
Personally, I prefer the 96 stock, not for its iconic sound which I will admit is good but because of the interior. I really like the lighter colour scheme of white/greg on the grab poles and the displays. If the northen line trains had black grab poles, it would be a close tie.
sometimes on the ‘96 stock you get the occasional orange LEDs on the dot matrix
What's the difference between the Central Line 1992 Stock and the Waterloo & City Line 1992 Stock.
Ah yeah that's a good idea. Off the bat, I know of the different grab poles and W&C being 4 car as opposed to Central being 8 car.
and the central line poles are red while the w&c line pole is turquoise
The doors used to be the same high pitched when the Northern was not refurbished yet
What about the "Drain"...?
Gk on the northen line and the jubilee line 1995 stock and the 1996 stock
The 1996 stock's motors are the GTO
The 1995 Stock's motors are the IGBT
They both have 3-phase AC induction motor
As for the two-tone sound, they used to be the same, but it appears the sound is played at a lower pitch after the 1995ts refurb, the same appears to have happened to the door closing chime. Here’s a video of the 1995ts before the refurb: czcams.com/video/xL_hGRJ8AGw/video.html
The 96 stock sounds like a Southeastern Networker
Another difference to note is the stickers on the exterior of each trains are different.
Hello @Nick Badley, can I remake this video?
Might've been wise asking me this *before* you used my clips without asking for permission, 2 weeks ago.
If you're recreating it again, then yes, you may.
Just in future, if you're gonna use clips from other people, always ask first :-)
What is the priority seat?
Seats for people that can't hear or are disabled 🤓
Nick heres a idea! Do this with the 1973 (picadilly) and 1972 (bakerloo) stocks!
