- How fast do the Class 800's Intercity trains accelerate, and how much faster are they than the much loved but ageing Intercity 125 High-Speed Trains (HST) . Enjoy this start from Reading Station heading towards Didcot Parkway to find out...
As a guide, the last Intercity 125 HST that i recorded starting from Reading to Didcot Parkway generated the following data: 0 t0 30mph in 53 seconds, 0 to 60mph in 1 minute 56 seconds, 0 to 100mph in 4 minutes 14 seconds, and 0 to 110mph in 5 minutes and 27 seconds.
If you are checking the distance data in the video, please note that an average HST reaches 7.9 miles in 6 minutes 16 seconds at around 115mph!

The GWR Class 800 and Class 802 are brilliant trains. Which it doesn’t matter if they on AC power or on diesel power. They still do have good acceleration.
Yes, but electric traction is unsurprisingly much better. Hopefully more lines can be completely electrified so the diesel engines can be taken out and they can go even faster!
@@thegreypenguin5097 i was wondering, why are they slower slower 395s despite being newer, but then I realised , the added weight of the engine system if likely the reason.
@@bb-3653they can go 140mph theoretically, but they can't because the routes they run on don't have in cab signalling, (HS1 has the French TVM signalling system) which means that you might whizz past signals before you have time to see them at anything quicker than 125mph
@grassytramtracks oh sure they were built for 140mph I know that. British rail lagged heavily behind after the 80s with any high speed route planns that they had with the HSTs which i think were built to handle 140mph. Kind of sad. Just HS1 at the moment has been built in a 40 year period of that proposal. I guess its all the UK government fault?
@@bb-3653 I don't believe the HSTs were ever intended to go 140mph in regular service. The fastest they've managed to hit on test was 143.2mph, but it's not good to run trains right up to the absolute maximum speed they can do because you'll wear out the engines. The class 91 intercity 225 was designed to be able to hit 140mph (the 225 is for 225km/h, which is about 140mph). The lack of in-cab signalling is the reason why they can't go faster than 125mph and they're now rolling out ETCS on the east coast mainline.
Fantastic video, thank you for uploading.
very good filming my friend. I love your channel.
Amazing video
Like the video very much.Take care.
What would be interesting would be to do a comparison between them on a different part of the line where the IETs run in diesel mode (and obviously an area where they aren't restricted by line speed), as there is very little publicly available data on the Diesel performance of IETs. It's known that they have a very good initial acceleration from standing due to their high traction, and it's rumoured that they have inferior 0-125 acceleration to HSTs but I can't find any comprehensive data on it. I also don't know how the difference in high early vs late acceleration affects the distance traveled over time.
The Railway Performance Society have published quite a lot of information on Class 800 diesel and electric performance on the following link. Feel free to download.

I have some Class 800 diesel v HST videos to post shortly 😀
It is a great honor for Japanese people to have trains made in Japan running in Britain, the birthplace of trains. From JPN.
@@envirommc7059 so what? The ageing train should be replaced by the new one. Again, why do you become so envy? How could you say they are piece of shit? That's so rude man
@青空太郎 - I went on the new Class 800 last week and it was great. Thank you Japan
@@envirommc7059 so what? I might don't know all about British Railway because I'm not a british. But you also know NOTHING about Japanese railways and you said their trains are shits. Come on man, don't be overproud like my people did.
@@envirommc7059 i appreciate your opinion, but making couples of trains is not easy man, they had to do many research before manufacturing them. Please respect another's works even if you don't like them by not writing such a rude reply to respective people. Railways nowadays is not only about nationality and history, but also about business and diplomatic relationship with another nation.
@@envirommc7059 i wonder why your mind is filled only with hatred...
Could these beat the 162 Mph record of the Class 9 if they were to be given an attempt at a record breaking run 🤔
I would imagine it would be around that speed. It's based on the same family as the 395's, the only different is less motorised Axel's in the speed department. The 395 did 156 in a test and hasn't attempted a speed record. The Class 390 is another locomotive that was said to be able to top out at 170, detailed in a planned attempt. The IET will probably top out (given it has the capacity to sustain 140 pretty easily in service) at around the 150-170 range, so it's up to speculation as to how fast it is. (I assume you're talking about Overhead traction, as the Diesel performance in the IET tops out between 115 and 130 depending on the gradient and environment)
The 162mph record was broken in 2007 by a 373 eurostar - 208MPH
Why don't they allow them to surpass 125mph on operational speed. Let me guess railways infrastructure doesn't support
Why was the Train terminating at Didcot Parkway? Normally they go to Bristol Temple Meads, Worcester/Oxford/Swansea/Cardiff. It is amazing how fast the class 800 accelerates, but the HST will be missed.
since 2 years ago, their routes have expanded across the south west. they used to run a few services only to didcot
i know these trains were built to cut costs, but did they really have to ride like tube trains at high speeds
Real progress running 5 cars packed to the rafters, dreadful things.
Trains should all do 0-60 in 6.6 seconds. There delays and travel punctuality sorted
I'm sure you're joking..
YEAH!! Still anyone opposing railway electrification? Anyone? 😊
I'm a member of MEGA: Make Electrification Great Again (ha ha)
@@ChangesOneTim Me too! (oops! )
it's sad to see diesels go but it is neccessary evolution
@@jakeytrainspotting1241 Exactly! I would never say something against the 1960s diesels. Good for that era. But today?
I will ALWAYS love you class 43 HST ..
Before you "Upgrade" ask yourself ONE QUESTION... What does this NOT do anymore??
I love HSTs too but time as arrived to say there old. However they still run from Cardiff to penzance with castle sets 2+4 and with XC, EMR
You cannot poke your head out of the window (taking great care to avoid it making contact with anything) anymore.
On acceleration and braking power, 800s leave HSTs in the shade. On the run out of Reading in this video, HSTs would pass Tilehurst at around 85 (the 800 managed 102), and not reach 125 until nearly Cholsey (the 800 did just after Pangbourne). For a lot of other things, such as ride and seat comfort, I miss the HSTs too.
Ask yourself what it does have!! Massively increased acceleration, air conditioning, free wifi, charging sockets, audio+visual announcements and sliding doors for accessibility, disabled toilets, etc.. We will all miss the 43s but it is time to move onto trains that can better serve future generations 🙂 And they sound nice too
@@crownjulesgaming542 better seats, better ride quality, better build quality (ie, not built with loose panels everywhere), wifi has been installed on the majority of HSTs, so were charging sockets
I was gonna say these are worse than the javelins in terms of accelerarion, but then I realised these have huge engine inside of them lol. So the added weight doesent help, so they are good for their weight.
@@Solomon_C oh really, the 800s are capped? Wow. Makes sense but I still think the A trains are slower than the 395 , at least until i see the full power stats. I wonder why 800s are power capped
Was it diesel or electric mode?
Electric mode
Didcot Parkway Services Should Be Served By Trains Simalir To Scotrail
Do PLEASE cut the terribly loud noises (music) at the beginning and the end. Thanks very much.
intro is roblox nezerra
This is class 802
I hope they electrify the entire gwr as far as possible to carmarthen, Hereford, Cheltenham, Basingstoke and taunton also Exeter
they will not elecrity to carmarthen they only go once a day each way electrity will only go to cardiff. will not do Hereford too or cheltenham. lol not basingstoke they dont even go there only turbos shuttle from reading to basingstoke. they are not doing exeter. this is why there diesel and electric
@@SionsTrainVideos I mean with elections out of the way ot is very possible. And again bi-modes can be converted to fully electric. And Bristol Temple Meads will be electrified from next year
@@profmargins the places i told you won't be tho
@@SionsTrainVideos I mean it all depends on the new dft executives
What. Why do we need all electric when they run on diesel aswell
How is it even fast when it goes exactly the same as HST maximum speed? This brand new IEP train are obviously have no change for speed when it only goes 225kph.
World High Speed Train Conquerer it can achieve 140, our infrastructure is shit so it can’t achieve that
Faster acceleration
@UkRailSpotter Hopefully, not for too long. Depends on whether in-cab signalling is actually implemented.
Both the pendolinos and class 91s were both designed for 140mph running but have always been restricted to 125mph and always will be.
@@DannyB16100 the existing signalling (as renewed over the last few years) is compatible with not only electrification but an in-cab system such as ERTMS. ERTMS can be overlaid on existing lineside signals but there would still be limits imposed by signal spacing (post-to-post braking distances), so it's best that ERTMS replaces lineside signals completely. For that to happen, all train types need to be ERTMS-fitted. Two other important things must happen before running above 125mph:
a) all types of level crossings must be abolished
b) ban on track workers going lineside while open to traffic
Both of these won't come cheap!
The motors are far too noisy and the soundproofing dreadful
I enjoy motor noise.
Me too
That is because the Brits did some cost cutting on the inside of this train.... Japanese design but built in England
My Hornby 00 Thomas the Tank Engine set from 1985 could accelerate faster than this bucket of bolts
😉
Not very fast. I rode one in China that was ridiculous.
chinese trains are crap, unless they are the imported ones from Japan and a lot of the are bullet trains
Nasty uncomfortable rubbish. I’m not interested how fast it goes. The HST you could sit in comfort and have a lovely meal at your seat. The 800s are a step back and I won’t be subjected to travelling on them.
your mum is an uncomfortable rubbish
There were probably people in the 70s saying exactly the same thing about the HST and comparing it to the A4 Pacifics!
@@B-A-L Lol that is a fair point, although at least the coaching stock was comfortable.
