A high speed trip on a Javelin from Dover to London

[@JenOnTheMove]

When I finished up on the South Eastern Main Line in July, I had one more video left in me... I've got no more South East based videos in the backlog for a good couple of months now, you may or may not be pleased to hear! South Wales next week!

The "walls" on HS1 are soundproofing barriers, to reduce noise for locals and wildlife

[@MikeWillSee]

Yep, it's just bizarre how they're located between the high speed tracks and the conventional tracks, because everyone knows that non-high speed trains famously make absolutely no noise ever /s

[@grassytramtracks]

​@@MikeWillSeeit's also because that barricade is also an international border, as in theory you could get through the tunnel to France

[@MikeWillSee]

@@grassytramtracks ah that's interesting, but still strikes me as a little bit strange because by that logic you could get through anywhere else on the railway!

[@noahbrock349]

Neither the Eurostars nor the Southeastern High Speed trains are particularly loud.

[@MikeWillSee]

@@noahbrock349 yeah the obsession with putting noise barriers along any new railway is always one that bemused me considering we have literally thousands of miles of existing railways existing quite happily without sound barriers but I guess that's the reality of building things these days

The Class 395s are nice trains, places in Kent is an area that I don't get to travel around as much. Great video Jen

[@RainhamRailEnthusiast]

So glad you enjoyed travelling on the class 395, they are indeed one of the best on the entire network in my opinion. Just hope the international services can stop again at Ashford and Ebbsfleet. Great video of the journey too.

Great vid, Jen. The last time I was on a Eurostar, they were still going out of Waterloo but they had built quite a bit of HS1 so we joined the line half way through Kent. I remember the sudden jolt of acceleration after we had crawled through the London suburbs!

[@mikemainer3009]

I would love to see Jen take a trip over to the continent and experience some real high speed train lines.

[@trevorelliston1]

I live in a country with no running trains. This year I had the chance to ride high speed trains in the Netherlands, Belgium and France. We hit 185mph or 298Kph. Awesomely smooth and fast.

[@officialmcdeath]

@@JenOnTheMove that suggests you took the quiet 'garden route' behind the British Library rather than going along the Euston Road - it's so much more peaceful as an interchange \m/

[@JenOnTheMove]

@@officialmcdeath I think I did go that way, yes! Several months have passed so I can't quite remember! I know everything was a bit tight on timing to catch the last viable LNR train to get back up north. It's actually quite lucky I decided to make this video rather than catch a classic service back... I was supposed to be staying in London for another couple of nights!

Loved the views and the Javelin. Seems very smooth at speed. Thanks for a bit of sanity n a mad world.

[@howardtaylor3837]

Glad you enjoyed the trip on my 395’s…. I say that as I’m one of the On Board Managers on those trains (we’re not Conductors as we’re not involved in train despatch). Samphire Hoe is formed of the spoil from the Channel Tunnel construction. The walls are to reduce noise from the HS1 trains. Folkestone West is a stop, as it has a huge car park on the opposite side to which you were sat.

[@marthaanderson2656]

Samphire Hoe is lovely and you can reach by bus It is notable for its rare wild orchids and if that is something that would please you, grab a botany friend and go.

[@thegrownupgapper3221]

It just goes to show that Hitatchi trains can be excellent if you get the spec right. You say the seats are commuter but they sure are better than those on an IET. The fact the Javelin's were bought partly for the Olympics helped them to be of a higher standard. It also demonstrates that after all the protests and agro over the building of HS1 many of us living in Kent wonder how we managed without it - Just remember that HS2 people, when you talk about HS2.

[@Andrewjg_89]

I do like the Class 395 Javelin and they are so smooth and so fast. And I have been on the Class 395 couple times and I really do like the announcement on the Javelin trains.

[@SuperLeonDenny]

Been fortunate to have been on the Javelins on HS1 a couple of times. Really love the trains and the speed too! Next step is to experience the Eurostar at 186mpb. ;) Also being nerdy the track work around Ebsfleet and Ashford is also mind-blowing with the under and over track work!

[@peterwilliamallen1063]

HS2 trains will be comming into Manchester, either by the link to the WCML at Handsacre or if the Metro Mayors of the West Midlands and Greater Manchester if they can get the finance a new high speed line between Lichfield and Manchester with a speed of 185 MPH which has been announced in Railway periodicals and on You tube

[@jackchapman5052]

On HS1 when it gets to Ashford International the top speed of a javelin which is a class 395 is 140mph when it is on the southeastern mainline is 100mph

[@Jothetrainneeek]

Folkesrone west has a similar passenger number to Folkestone central but it’s unreasonable to make passengers only go to one as Folkestone west has a massive car park and central has hardly any but central is near the town centre

[@MichaelSebastianTodd]

brilliant video i havet been on a Javelin train since 2018 & i def want to ride down HS1 again in the future & i def agree its a shame HS2 wont go to Manchester & still gutted about it & the North deserves to have better train services

[@Bob-85-yt]

You should try Eurostar if you want to go as fast as possible in the UK!

[@jacobporrett]

Thank you for sharing Jen

[@dazlebluefrogify]

As a frog (born in manchester to english/french parents) i take the hst for granted over here ,my first one was back in late 88 when i did Paris to Grenoble loved it ,the Tgv as we call them had the line only to lyon then onto the classic line back then ,caught a eurostar years ago but came out of Waterloo , i'm sure back then some stopped at stratford and ashford ? Why have they stopped doing that ?

[@airfoxtrot2006]

Excellent video Jen 😊

[@Southeast_spotter]

Hi Jen the wall is would Barriers to protect the south eastern mainline and the M20, and there is no southeastern service the goes on hs1 before Ashford becuase there is no physical connection between the freight yard on hs1 and then south eastern mainline

[@suffolkraider]

I've stood in Ensign yard and got some good footage of "christ that's shifting" trains lol. Been on HS1 once and yes the acceleration ! Also stood near the Medway Viaduct and the noise is brilliant

[@SteamboatWilley]

I had a similar impression on my first trip on a Javelin. While they are undeniably fast and good looking on the outside, they feel like an ordinary commuter train on the inside.

[@CurvedGD]

The only good Hitachi AT300 in the UK, and the original! Glad to have these as my local services alongside Ramsgate - Victoria services, giving me two ways to London in around 1h30m from my coastal town of Herne bay (of which has a GORGEOUS station and I highly recommend an in-depth visit to Herne bay when you do the Chatham Mainline) Also, that train at St Pancras was not terminating at Sandwich. Southeastern advertise St Pancras - Ramsgate Via Dover Priory as only terminating at Sandwich because SE want passengers to take the faster St Pancras - Ramsgate via Faversham and St Pancras - Margate via Canterbury West services due to their much faster journey times. All but two services end up in Ramsgate. those 2 exceptions being the St Pancras - Faversham (which layers with other services on the Chatham mainline providing a 15 minute or less frequency between Rochester and Faversham) and the limited St Pancras - Maidstone West services. Doing every station in the medway area of the chatham mainline is easy, doing the Faversham - Dover line is a pain. (hourly)

[@leona_devon]

OH yes, nice, took the HS1 EuroStar from St Pancreas to Paris, then the TGV to Spain, which really puts our trains to shame, double decks, really really fast! Actually comfortable, reclining seats, USB charging wifi, oh the luxury, Europe know how to do trains, sadly the UK doesn't :(

In theory, it is possible for trains heading towards the Channel Tunnel to access HS1 via Dollands Moor yard (between Sandling and Folkestone), however that route is purely for freight trains

Samphire Hoe is a nice cycle ride from Dover so you could do a fun "how hard is it to get my bicycle to Dover by train" video (and "where the heck do I put my bike in a Javelin?") Once you've got up the hill to Samphire Hoe, carry on towards Folkestone to see the concrete ear (before radar attempt to hear enemy planes) and then there is a massive descent into Folkestone to the fabulour Harbour Arm aka Folkestone Harbour station.

[@shawnd-v1660]

[@BlargMeister]

this was filmed just a few hours before my eurostar service arrived back into st pancras from brussels! it's such a shame not being able to get international services from ebbsfleet anymore as it was quite convenient for me in 2017 to get from north kent to paris. I would definitely still use it nowadays if it was still possible :/

[@harryelliott4310]

Trains Station 🚉

[@imsbvs]

The train very grubby, there is currently a programme of refurbishment underway, including USB B & C ports added to the electrical plug sockets. Be careful when near the coast as at times I have connected the French mobile network, these days roaming charges might be applied! At Ashford, whilst in the station the train switches from 3rd rail (which is limited to 100 mph) to overhead power supply, on HS1 these trains run at 140mph, but Eurostar run faster at (about) 183mph - and Eurostar has been known to be difficult if one of it's trains is delayed by a slower Javelin train. I think HS2 will be run to Manchester, albet nearer the 180mph speed than the 200+mph speed south of Birmingham.

when you do faversham, a good way to get that whole region done would be Faversham to Dover via Canterbury East then to Ramsgate via Deal then up to Faversham via Herne Bay do love HS1 tho, nice video

[@SiVlog1989]

The only way you could go faster is on the Eurostar, the 395's (aka the Javelins) "only" reach 140mph, while (depending on whether it's the newer or older units) Eurostars can reach either 186mph or 200mph

[@stanley3647]

Javelins are build at same base as 8xx fleet (Hitachi A train) - these comming now into UK mainlines. Just different body (HS1 is build with bigger train gauge, than standard BR), but techically is almost "same" train. But lack of investments into UK rail infrastructure (No ETCS level 2) , make other mainlines limited to 125MPH(200km/h).

[@joshmarsh2532]

​@stanley3647 ETCS level 2 is slowly being rolled out on the ECML but the 140mph will never happen because there's not enough free capacity on the line. There's also very little point as the time savings would be minimal and the capacity reduction would be significant

[@stanley3647]

@@joshmarsh2532 Extra speed (140MPH) today only make sense as "extra speed buffer" for delayed trains. Maybe some non stopping services with enough room on route as well... Gain is marginal (few minutes per 100 miles). If trains stops more often - this is pure waste of energy... PS. If You remember IC 225 (Class 91) technically was a train which was able to travel at this speed - and this was 2 decades ago...

Not even protecting the land was so short sighted it's painful

[@peterwilliamallen1063]

Where did you get that one from, the plans were in the 70's but fell through, the present HS2 line has never been planned to join up to HS1 as it is purely a domestic high speed line to speed up services on the WCML from London to the West Midlands and the North after the twice failed attempt to upgrade the WCML from Stafford to London and produce more capacity for freight on the Southern Half of the WCML plus HS2 is billed as one operator line being operated by Avanti West Coast Trains and it's partner Trenitalia Trains

[@networkerfan]

@ because flying is incredibly bad for the planet. airlines and airplane companies have tried to make planes greener but its an incredibly difficult job that will take an extremely long time. which we don't that time to tackle climate change before its too late. so we should be doing whatever we can to reduce the number of planes

[@peterwilliamallen1063]

@networkerfan What utter rubbish mate, what is more damaging to the planet is a Volcano erupting as proven when the weird named Volcano on Iceland blew it's top about 8 years ago grounding every aircraft from the Arctic Circle to the Mediterranean for weeks, modern aircraft are wonderous things that emit mainly water vapour out of their engine's exhaust, they transit the globe taking people on business trips and Holiday all over the world, they transport goods to us, they delver emergency aid to troubled countries, they protect us in times of War and Piece and above all they are one of the safest ways to travel from A to B and take you in sheer comfort on your Holidays. Climate change as we know is utter crap as the Earth is not only destroying itself but from the day it was formed and the first dinosaurs farted and will continue till in millions of years either Volcanos or a Nuclear War destroys Earth or the Sun will destroys the Earth even you eating sprouts and Turkey at Christmas laughing while you fart watching the Kings Speech is affecting the climate so Climate change is a big joke and why should I and many give up my flying, petrol and Diesel cars and Gas Boilers in the UK when 3rd world countries won't bother plus Trump is not interested in it, so to answer your other question there is no call for passengers from Birmingham or Manchester to catch a train to Paris or Brussels, the amount of passenger from Brum or Manchester to Europe would not even fill a coach on a train when it is quicker, easier and faster to Fly. I bet you go abroad and fly, even Cruise Ships belch out exhaust fumes. If you want to know about polluted environment, take a look at London between Victorian times and the early 1960's, you will see the City enshrouded in a dense fog/mist called Smog a combination of dirty smoke from Factories old fashioned cars and steam trains mixed with Fog which caused untold deaths and I remember it in Birmingham in the 1960's and this only ended with the Clean air act banning coal fires and factories using the burning of coal for production, the environment we have now is perfectly clean compared to the past, so no we dont need to or want to reduce the number of planes, god I do love flying

[@ThomasArkwright]

Anything without in-cab signalling is limited to 125mph on the entire UK network. I imagine since the javelins have in-cab, signalling since it's required for HS1, they could maybe go 140mph in some areas. I assume the schedules on conventional tracks assume a maximum speed of 125mph though so you're probably right with it only being during a delay

[@samuell.foxton4177]

There was a time when they did 140mph, but safety concerns over signal sighting (as it's conventionally signalled rather than using the TVM system like HS1 does (HS1 is essentially a French TGV line in the UK in terms of engineering and technology)) ETCS Level 2 is currently being installed on the ECML (and, I believe on the GWML at some point), which will enable 140mph on those two lines since the IEPs are capable of it
