I've taken my car through "Le Tunnel" as its now known. It's an expensive option on the surface, but I prefer it for convenience since you have your car on the other side, and it is very fast. Only 20 minutes really if you exclude the boarding process which is surprisingly fast and efficient (ferry is like 2 hours depending which route). You drive onto a double story train, the train cars seal off between each other, there's 100 safety announcements, and you're on your way. You do not leave your car ever. I think what's more fascinating is that you're going between a right hand drive country to a left hand drive country, you could do a video on the associated road infrastructure which transitions you between the two so seamlessly.

As someone who's taken the Eurostar several times, I can assure you it's far better than flying. There's a reason why those fights have to be cheap because they have to undercut the price of the train. The train will offer far more comfort, space, and amenities than those typical short haul airliners. Being able to leave downtown London and be in downtown Paris within 2 hours is amazing. Depending on the price of the ferry, the automobile driver can choose to take the train all the ferry. I once traveled from London to Munich all by train. First leg was the Eurostar to Paris and then I took a TGV from Paris to Munich. Sure, I could have saved time by flying straight from London to Munich, but the train trip was far better. During my stopover in Paris, I was able to explore the city before catching the next train.

I agree on the flying bit. But when traveling by car, the ferry is far superior to the shuttle. It is often cheaper, takes about the same time,including wait times, loading and unloading, and on the ferry you can walk about and have lunch.

Also, both the planes and the ferries are petroleum-powered. The electricity that runs the trains COULD be from petroleum, but it could also be from other sources, particularly wind. And the electricity doesn't care if and when it comes from another source. So, if we find out tomorrow that putting a Ficus and a house cat in a room with an aluminum floor generates massive amounts of electricity without harm to the plant or the cat? That will be powering those trains.

I’m from the U.K. and am right now currently skiing in Austria having taken the channel tunnel here and will use it to return. I have used it twice a year for twelve years and the logistics behind it all is immeasurable. The trains are very punctual, they’ll load more than 100 cars in 15-20 minutes and provide this service four times an hour in off seasons and six to eight times an hour in peak holiday seasons. And even though it was designed now almost 40 years ago, the trains and every looks modern still

Another nice detail about the channel tunnel is that it allows new built trains to be transported from mainland Europe to the UK without needing to be loaded onto a boat and floated across, resulting in lots of faffing around to get them on and off, simply hook the train to be delivered to one of the tunnel freight locomotives and they can be pulled through. It’s how the new Mersey rail and Tyne and Wear metro trains are being delivered from stadler in Switzerland, they get pulled by train to Calais, transported through the tunnel, and hooked onto another train for final delivery (usually a pair of Down geared HST powercars)

And the ride was suuuuper smooth. There was just one spot where we felt an ever so slight bump, the rest not a single vibration. It was also cool to get off the coach and walk around in that huge rail car, meeting people from other coaches.

That is so cool! I've always been interested how our underground Metro system (subway) works here in Montreal, Canada, and the idea of travelling the channel tunnel sounds so cool!! Does coach mean travelling by bus? When talking about travel in English, I usually see coach as a category of ticket and seating (like first class is most expensive for more comfort and features, and coach is least expensive for the least features and comfort). Unless it's about _historical_ travel by horse pulling a carriage or buggy, then I see it often referred to as coach! But unless it was a _very unique_ travel agency, I don't think that's what you meant, haha 😁 But if it was I need to know the agency's name immediately because that would be _fascinating_ to look up!

@@becauseimafan I've done this trip a few times (maybe 30?) in the last 20 years, and all but one has crossed the Channel through the tunnel. (In the UK, we call it "the Tunnel" not the "Chunnel" - there's no better way to look like a tourist :D ) The coach is simply a long-haul bus but with an onboard loo, USB charge points, better seating (usually - I've had some Flixbus journeys that wouldn't have been legal), curtains on the windows, more luggage room, and infrequent stops. The bus generally leaves and arrives on time, there's no passport control when you board (that's taken care of in Folkestone or Calais before you go through the tunnel), drivers only want to see your ticket and ID to show it's yours, so boarding is MUCH faster than on a plane. Sometimes there's luggage scanning when you go through customs. The bus takes longer than a plane, and is often around the same price, not including luggage, and around the same level of comfort. But if you don't want to fly or drive, this is the way to do it.

I am proud to say that I contributed to its construction, in a small way. I worked there as a loco driver for a couple of years, with the hand tunnelling gangs that dug the cross-passages and piston relief ducts on the land drives. Made a few trips to the marine TBMs, delivering ring segments and grout. Quite intimidating machines, the first time you drive inside one. They're huge. The crossovers were even bigger before they put the doors in. I still have my tallies, a TML t-shirt that still fits, and my breakthrough medal. Oh, and a 5lb ammonite that I pulled off the conveyor belt, before it disappeared for another few million years. 😁 Best wages this part of the country had ever seen, which was a bonus... The disadvantage was that now that HS1 is open, people from London have moved to Folkestone in large numbers, pushing house prices through the roof.

A few megaprojects in France right now : There's the Lyon - Torino line currently being built, with a gigantic base tunnel between France and Italy (duh). There's parallel digging and there will be deep "meeting" too, at a point located close to the vertical of the mountain peak. The base tunnel will be slightly longer than the Brenner Base Tunnel. And also the Grand Paris Express, a humongous metro expansion (200km, 68 new grandiose stations, 4 new fully automated lines including a circle one that is the longest fully underground line, plus 2 extended lines). Some stations have more than 50 escalators, about 9 kilometers linear of platform screen doors on the circle line only... First bits are set to open this spring 2024, first section of the huge circular line in autumn 2025, then one or more sections every year till 2030 or 2032. And there are also the recently relaunched high-speed line developments, especially in the South, like the Southwest triangle from Bordeaux to Toulouse and to Spain on the Western side of the Pyrenees. As for the question : when they pierced the hole at the meeting point there was no blast or sudden rush, but a constant rush of air as the tunnel acted as pipes. You can see it on archive footage with the flags at the meeting point.

The route was 'simple' enough, drive from Vaasa to Turku, a ferry from Turku to Stockholm, drive across the big bridge from Sweden to Denmark, keep driving and the Chunnel awaited. Drive onto the train, twiddle thumbs and get off in Dover - then a big drive west. The second was returning the van!

You can now travel by high speed train from London to Amsterdam, Brussels and Paris. The tunnel did mean the end of a more amazing means of crossing the channel, the massive hovercraft that did the trip in about 20 minutes with or without your car.

Those massive Hovercrafts were a feat of engineering as well! Only seen a couple when on a highschool trip to London in the 80's when we were crossing by ferry from Calais. Most impressive was in Dover where they came into port and "floated" in to "land" wit all the noise from the engines and propellers!

This is my favourite way of travelling to the continent. Especially the car shuttle service. I like that one. The whole thing is weird and wonderful and I love it. The cool thing about the pricing is that if your car is full of people it still costs 1 car to cross not 4-5 people. It is by far one of the cheapest ways to travel in some cases even with budget airlines.

I took the conventional ferry across the Channel on a beautiful sunny August day in 1983 in the middle of the day and it was absolutely fine. The Channel was as smooth as glass. I'd been worried about nausea/seasickness and had dramamine but didn't have a moment of difficulty. I wish I could remember the duration of the crossing - and the endpoints for the ferry - but I *think* it was about 3 hours. The next time I crossed the Channel was in 1991, this time by hover ferry. Again, I don't remember the crossing time but I *think* it was about 90 minutes. This was also a totally trouble-free crossing. I would happily take either trip again. I haven't taken the Eurostar yet so maybe I'd like that even better :-)

Been in the chunnel quite a few times since it opened. First in 1994 as a kid, then in the 2015-2023 timespan to go to conferences. The Eurostar is a great and comfortable train. One of the conferences was *in* Folkestone, and the passenger train only stops in London (requiring at least 2 hours of additional travel), so I brought my car along as a ticket to get off in Folkestone. The Shuttle service is pretty fast, but I will choose the Eurostar if they are otherwise equal. Shuttle has longer delays and wait times before you can board, and everybody's carrying their car onboard so boarding takes a long time.

I'm a Londoner who regularly uses the Channel Tunnel. Attempts to build a tunnel from England to France date back to the 1800s. One thing not mentioned is that there are two enormous, naturally occurring caverns, which the engineers utilised as crossover caverns, so the trains can switch tracks if needed, and I've noticed on occasion entering on one side and exiting on the other. I can confirm the temperature in the tunnel is pretty warm, you'd only notice it on the shuttle while moving between carriages. The Eurostar is the high speed passenger only train leaving from St Pancras in central London, and goes direct to a number of North European cities like Paris, Brussels, Lille, Amsterdam and some others. The Eurotunnel Le Shuttle is for vehicles only and departs from Folkestone, close to the coast in South England, and only goes to Calais in France. The novelty never gets old for me and it's just the best way to get to Europe on either service. It's more expensive than the ferry or flying, but it's way faster, and vastly better for the environment than flying. Plus with the Eurostar you arrive in the middle of the city, which is dreamy! It's definitely not a white elephant, whoever said that from the BBC was smoking something... Great video as always!

Several years ago on my first trip out of the country I went to London, with a planned day trip to Paris. I just HAD to take the Eurostar, the thought of taking a train underneath the channel was too good to pass up. The whole trip definitely didn't disappoint. Much easier than taking a plane too; center of city to center of city with minimal lines and passing through customs before you even get on the train. I would definitely do the trip again.

That adds up to flying having TEN TIMES the emissions per passenger km, as aviation fuel is pretty dirty and it's even worse when you inject it high into the atmosphere. Really, flights between London, Paris, Brussels and Amsterdam should be banned now. But the train needs to be cheaper too.

In addition to people and freight, the tunnel is transporting massive amounts of data between Europe and the UK (and from them the US) As a network infrastructure operator, the tunnel has huge competitive advantages over classic undersea cables : very low risk of fiber cuts, no need to transport power for the amplification and easy maintenance that don't require specialized ships, undersea robots, divers and a calm weather. And adding capacity cost virtually nothing. The competition on that route is under one of the most busy shipping route in the world with a bad weather, which complicate maintenance by cable ships This data activity is a massive cash cow for the tunnel operator that came as a surprise for this pre internet project

The unprecedented peace we've enjoyed in Europe has given rise to some of the greatest advancements in history.

Ferries are the better choice if you're travelling from the South/Southwest of England to the North/Northwest of France. To travel from Portsmouth to Ouistreham, for instance, takes 5-6 hrs on the ferry versus a 7 hr + drive via the tunnel. Plymouth to Roscoff is a 13 hr, 735 mile drive via the tunnel, or a 9 hr, 120 mile ferry crossing. Depends on lots of things including preference, cost of fuel and so on!

I've been through the tunnel a number of ways. The simple crossing from Folkestone to Calais is good, but where it really shines is when it's part of the wider rail network. The simplicity of city centre to city centre travel with room to move and no painful airport parking and terminal experience is great. Sadly after Brexit and Covid the number of destinations available direct from London has been cut to only Brussels, Amsterdam, and Paris. It used to be possible to get a direct 'Snow Train' to the French Alps during the ski season. That was a fantastic way to go skiing when we had a tiny baby. Obviously it's still possible to cross the channel and then change trains, but that loses some of the appeal when you're traveling with luggage and small kids.

I've used the channel tunnel many times to go from the UK to France, mostly on family holidays, with 6 of us in my van. It's cheaper than flying, and lower on emissions. Yes, it's a bit slower (particularly as I have to drive 180 miles to get to the tunnel in the first place, but live in a town where I could get straight on a ferry), but if you want to take a lot with you, then it's difficult to beat. It's an amazing thing getting in the train in the UK, and being in France half an hour later, and just driving off into a foreign country. Ferries are generally more expensive than the tunnel, and while we did it once, it was an underwhelming experience. Great look into the project, quite a bit I didn't know about it in there. Thanks!

Finding out about the different ways that this is managed during big tunnel projects was fascinating. It becomes a whole project of its own that involves transferring the spoil in an environmentally responsible manner, keeping dust levels down with water spraying as well as managing any residential concerns when relevant. And then there is all of the vehicles required, both inside and then outside the tunnel to transport the spoil away. The infrastructure necessary to keep both workers and equipment on site and ultimately where the spoil goes etcetera Anyway, thanks for sharing this video with me. Much appreciated as always.

There is also a high-voltage DC line in the Euro Tunnel. This connects the high-voltage AC network on the mainland with the high-voltage AC network in England. It allows electricity to be transmitted in both directions, as needed. In continental Europe there is the connected power grid and in England, Wales and Scotland there is the English grid. Both networks sell and buy electricity from each other on the European electricity exchange. This leads to a high level of reliability because many power plants are networked.

For someone who was already in London for work but didn't have access to a car and didn't want take a cab to Stansed (where most low cost short haul flights take off from), taking the tube to St Pancras and hopping on the Eurostar was SO EASY. Also, my return trip was business class since regular tickets were sold out. The private seat and food service were amazing. Definitely a good way to wrap up a long day walking most of Brussels by foot.

I actually prefer taking the ferry to europe instead of the train, despite being a big rail fan. I'm over 3 hours of driving away from the south coast, and having an hour and a half on the boat to get food, get some fresh air and even just to take in the coastline before you arrive is a really nice pause, and allows your brain to reset before continuing your drive on the "wrong" side of the road. Plus it's about half the cost of the train, which is nice.

This is less of an issue with the Chunnel itself, but I think the reason it has been relatively poorly utilised is that the UK hasn't really tried to expand the reach of service much. St Pancras is a huge bottleneck now, not because of the platforms, but because it simply doesn't have the amount of space an airport does to process passengers. Track access charges are very high for HS1 and limited effort has been made to expand service northward, or try to connect up HS1 with our other mainlines and what is left of HS2. I'm glad you mentioned this in your video, that frustratingly, Eurostar is not an economical option for many outside of London. You are paying full price for a ticket into London and because of your more limited journey times, are unable to take advantage of off peak fares on Eurostar, which is surprisingly expensive!

I was in London with the family for a week (4 of us) and fancied going to France for the day. We were looking at about £900 to go by train, or £80 to take the car from Folkestone. I'd say the passenger train is just a little overpriced, like every other train in the UK.

I have taken the Eurostar trains from London to Brussels a few times over the years, it was a pretty good experience. There have been several rivals to conventional ferries for crossing the channel. Such as the hovercraft between Dover and Calais (1968-2000), disappeared after the tunnel opened. There was a short-lived hydrofoil (Boeing jetfoil, Brighton to Dieppe) aimed at business travelers from London to Paris, opened in 1979 and ran only to the early 1980s. One niggle, the High Speed 1 (HS1) line through south eastern England shortened travel times from London to the start of the tunnel - but Eurostar services from London using existing infrastructure started in November 1995.

Great video, my father who sadly passed 2022 would have loved it, and im sure probably offered up lots of additional extra details. One of the topics you touched on was a real worry for him as he was a tbm driver. In previous surveys of the channel they did not originally fill in with concrete after taking core samples, so those holes would slowly silt up. If they had ever hit one of those it would have cost them a tbm or three, but they had very beefy emergency pumps to prevent total losses. After the job and then the jubilee line extension, he eventually worked for euroscan, so the tunnel was really a major part of his life.

It is still being used by tens of thousands of people and heaps of freight per year, so the term white elephant is a bit much. Then again, I am an engineer. Accountants be damned - some things are more interesting than money.

Grady, another fantastic video. If you have information on a couple of things regarding the tunnel (I could look it up but it's far more educational when you explain it) . #1) How is the air quality managed thru the entire length of the tunnel, so it remains healthy for humans? (this must be an incredible engineering feat in its own right). #2) How are medical emergencies or mechanical failures, like people getting sick, engine failure, running out of gas, crashes and other common problems addressed? (Hospitals, Ambulances, auto repair shops, tow trucks, 7/11's)? #3) Is the pumping of air thru the tunnel used to spin wind turbines to produce power for lighting or other uses? (I have seen this done in several North American Tunnels). Thank you sir, your videos are always very interesting and educational.

@@scbond While the PracticleEngineeringChannel host did cover a great deal of information, it was largely focused on the project design, engineering, problem management and construction with some interesting operational solutions also discussed.

Thanks for all the handy illustrations! I have to question one point though: The numbers at 13:00 seem highly unrealistic to me, some quick googling later I found a figure quoting a factory worker at one of these cooling plants. They gave 7°C or 44°F, which I find way more believable for one of Europes biggest cooling system ^^

Sorry for the confusion. That could have been worded better. The refrigerant temperature is indeed much cooler than the numbers quoted, but the maximum design temperature for the tunnel itself was 35C, 95F.
