Have travelled to Germany for almost 60 years never depending on a ferry. So your text is somewhat wrong. Not revoluuutionary as you express it. Denmark is connected with motorways and bridges and has a north-south bound motorway leading directly on A7 through Germany crossing the landborder. But it'll shorten the traveltime for some Scandinavians, though most Danes don't live in Copenhagen. And the idea for a connection doesn't only date back to the 1960's. It was discussed in connection with the big 'H' plan back in the 1930's, -the future infrastructure plan for Denmark. Though at that time it was downgraded to establishing a ferry connection instead.
Amazing project, the video however not so much! - The project is in the Femern Belt and not the Baltic Sea. - The current ferries are not small and cute like those shown in the video, but rather big ones able to transport cars, trucks and trains and something like 1500 people at a time. And there is no hills/mountains on neither coast line, so those pictures are also just random grabs that are totally misleading.
Scandinavian Chunnel, much? Maybe different techniques but the goal is very much the same, a more unified and prosperous Europe for all! I'd also love to see the Rostock Bridge or Tunnel also be considered to allow a stronger connect to Berlin in the future as well!
Except the existing "chunnel" is trains only... This one will beat the current longest undersea road tunnel by about 3.5km, only to be beaten a few years later by Rogfast ("fast" here not referring to speed, but being the Norwegian word for "fixed" or "permanent"), currently being built not far from the current record-holder Ryfast. And yes, the Fehmarn tunnel has little in common with the Chunnel, while Ryfast/Rogfast are traditional, bored-through-solid-rock tunnels like the Chunnel.
During building/assembly: Special anchors, mentioned in the video. After building: The whole thing is sunk into a deep dredged "ditch" and covered by rocks and soil. This can be seen in the video. I think it was mentioned that the ditch is 20 meters deep (not gonna re-watch - you do that if you want to verify). The elements have a height of 10(ish) meters so there will be maybe 10 meters of rubble on top of them. The technique is not new. Same thing was done on the tunnel in the Øresund connection between Denmark and Sweden which was inaugurated year 2000, and those elements have not surfaced yet 😅.
The concrete segments have extra pipes from one end to the other parallel to the pipe for cars and train just smaller. While these pipes are empty the total weight is less than the displaced water, but once filled more heavy than water displaced. These extra pipes are made so the segment can float to its position and before being filled and the segment released into it's final position. It's pretty simple.
😂 That figure of speak pokes me also. Eg there was/is a TV series about tech evo- and revo-lution which always ends with "[...] making the impossible ... possible".
@@davebowman6497 Yes I have seen that. Also one called "Impossible Engineering". These people need a dictionary to look up the definition of impossible.
Pumps nothing shocking! Pretty much all tunnels like this do the same if the pumps are turned off then said tunnel will ultimately fill up though will take a rather long time to do so
@@ManfredPrefi Watch 4:04 and 6:56. There's a trench in which segments are placed. It's covered with ballast afterwards. I think you can the tunnel ends up under the seabed.
Re: (Tunnel) "...is designed to handle modern transportation demands." Does verticle tunnel height allow for double-decker passenger train carriages, also double-stack cargo trains?
European double-decker passenger trains are not significantly higher than regular passenger trains. Double-decker cargo trains are rare to non-existent in Europe. Those trains that are already running fit the current bridges and tunnels. By simply following the existing standards there never will be an issue. And besides that; with a project of this scale, do you REALLY think they haven't thought about that?
Every country has a "loading gauge" for their railway system. It defines maximum height, width etc for trains on that system. With the possible exceptions of very old segments or rare special cases, tracks in a specific country are built to those specifications. (Maximum allowed axle load can vary within a country, depending on eg the quality of the trackbed and tracks etc). Loading gauges are mostly similar in most European countries (Great Britain being an exception with a substantially smaller load profile - for historical reasons.) It makes little or no sense to over-dimension one small segment of a rail system compared to the rest of the system, as any train utilising this larger load profile would not get far before it encounters a point where the standard load profile holds. Updating the load profile for a whole country, or even large parts of Europe, would be extremely costly. Extremely! The cost of the Femarn belt connection, even with an enlarged load profile, would be pocket change compared to making a meaningful enlargement of the load profile over a larger region. There are special cases where an upgrade makes sense- typically where there is bespoke rail traffic over a shorter distance. Prime example is the Iron Ore Line in Sweden, which carries Iron ore and iron sinter from the mines in the north of Sweden to the harbours of Narvik in Norway and Luleå in Sweden. The whole line is 398 kilometers long. It has been upgraded several times, eg to accept a higher axle wheight (highest in Europe) and longer trains. But a fully loaded iron ore train can not venture beyond the Iron Ore Line - those trains stay on those 398 kilometers. There are already double-decker passenger trains running in many European countries, and if they fit the German and Danish loading gauges they will fit in this new tunnel. I'm not sure about double-stacked containers, but a quick look at eg the German loading gauges suggests that the "rectangular section" that could accommodate eg a container has useable height not greater than 3 meters or so - so no double stacking there. And so it makes no sense to build the tunnel to bigger dimensions, unless there is an enormous need to haul massive amounts of containers the 20 or so kilometers between Rødby and Puttgarden. There isn't. So, how do they get away with double stacked containers in the US? Answer: Diesel locos. No overhead electrification. Loading gauge is 6 meters high or more where they can do double-stacking. For anyone interested, there's lots of info in the English Wikipedia article "Loading gauge".
@@davebowman6497 The country of India has recently been able to run electrified double-stack container freight trains on specially prepared rail lines.
Yup (but maybe not "way more"). Assuming 90 km/h (same as in the Øresund tunnel) it will take 12 minutes. (Theoretically. In practice 12-15 minutes seems reasonable.)
Except it gets things wrong and is loaded with misleading video segments. Like the silly depictions of ferries which, with a few exceptions suggests, show the current ferries as tiny clearly short distance ones sailing from places with hills ie. nothing like the reality. Same thing with the clip of the weather conditions in the Baltic, as again the pictures shows a coast with hills if not mountains not to mention the construction is in the Femern Belt and not the Baltic Sea.
"For decades travelers between Denmark and Germany have relied on ferries crossing the Femern Belt" What nonsense! What about the 68 km landborder between Jutland and Schleswig Holstein?
Es stimmt; wir sind lange Zeit mit Fähren von Dänemark nach Deutschland gereist. Wir sind aber auch Jahrhunderte mit Pferdewagen gereist, trotzdem geht es mit Bahn und Auto schneller und bequemer, und wir tun es. Deshalb kann ein Tunnel kein Unsinn sein.
@@ManfredPrefi It's nonsense that the traffic between Germany and Denmark rely on ferries. The majority of traffic between the two countries are already going by truck, car or trains via the 68 km landboarder and A7/E45. By the way if you germans, want to make the travel to Denmark more efficient, maybe you should upgrade the Infrastructure at the 207/E47 and the parallel railway, which is a one way track and a two lane road, and upgrade the Fehrmarnsundbrücke, so it can support heavy freighttrains. Right now the project will be finished with a superior tunnel and danish infrastructure, but pathetic german infrastructure.

You claim that the Fehmarn Belt Tunnel (18 km/11 mi) will be "The World's Longest Underwater Connection". Have we forgotten about the CHANNEL TUNNEL (an underwater rail tunnel, measuring 37.9 km (23.5 miles)??? The Channel Tunnel has the longest underwater section of any tunnel in the world... and is the third-longest railway tunnel in the world!
Good video. Too bad that the german side(DB) is stalling the completion of the project. There ism't even a startdate for the constuction of the final link between Femern island and the german mainland. So far they just upgades the old one-track and two-lane bridge from 1963.
It is. Much of the traffic comes from the island of Zealand though, and taking the route over the Funen island and Jutland (which is connected by land to Germany) is quite a detour compared to this new tunnel connection. Not only does Zealand hold half'ish of Denmarks population. It is also the island over which the bulk of transports from Sweden and (to a lesser extent) Norway transits to reach the continent.

@@TecraTube Umm, Just as cars have to enter a tunnel on both ends, so does the air. Let's think about this for a second. You really think they would come up with this type of solution if they didn't think it could work? I'll trust the engineers instead of some random person on youtube. Continue your fight though.
@@TheRailwayDrone Re: "I'll trust the engineers....." granted that your thought process is valid. Hover, engineers are not always the decision makers. Recalling a report years ago by a Consultant group, the recommendation of a roadway tunnel was presented for a short, time-limited review. Part of the tunnel proposal included: # Cross-traffic signal that would have caused vehicle back-ups into the tunnel. # No fan or forced-air ventilation; motor vehicles would "push air" through by their movements. # Adjoining walkway would feature illuminated signs when carbon monoxide levels would "exceed normal" level (Woe to motorists or wheelchair users who have a medical condition!). # No mention of emergency pump system to de-water since location is near sea level. After a final public hearing at the Convention Center, a bascule bridge design was decided upon and approved. It was claimed by some that the choice taken was mainly financial since a bridge structure cost less than a tunnel
Again: There are many tunnels using fans like that. And the tunnels under water are just as airtight as the ones under land. I.e. not. And there are already other tunnels under water using fans for exactly the purpose of ventilating bad air out and fresh air in. On the subject of these fans, the engineers are definitively the decision makers. Your "air tight" amply demonstrated your level of expertise. But as others said - do continue your fight.
The longest combined road and railway underwater connection. You are not able to drive a car through the Chunnel. You have to load it onto a train. Thus the Chunnel is considered a railway connection only. Two different beasts. The Chunnel had a whole lot of extra challenges and had to choose a rail-only solution for a lot of reasons. However, the solution used for Femern (Danish spelling) could perhaps be used for the Irish Sea? Going from Scotland near Portslogan to Whitehead in Northern Ireland? I know that there is a problem with the area having been used to dump unused bombs and ammo, but that could be cleaned up.
I am sure Denmark will finish this project as planned BUT I note that the German´s, that do not contribute one dime to the connection, have promised to build and connect train lines in Germany to the tunnel have not even begun. The Danes began building the tunnel with this promise in mind as it will be a crucial part of the repayment of the invested capital. Right now Germany have a higher unemployment than for a longer time. Maybe time, Germany, to work on materialising the trainlines so the tunnel actually can function as planned. Honestly, Denmark are building a tunnel with designated tunnels for trains and might risk they will be useless, because Germany might not be ready to harvest the free orange that landed in their turban. What´s going on German?
Well, DB is planning to get everything built up to 2029, which would be fast if you see how long it could take in Germany to become able to start legaly because of all the regulations and possibilities for the public to go to court against the things the developers planned. If you look to the danish side, litaraly no one lives where the laying the tracks to Sundby, on the german side there are 88 kilometers to built crossing through several cities and villages - and every neighbour of the new track can oppose the plans and at least go to court. That takes time, much time and is a pain in the ass - but we're not in Japan, where the goverment can take your ground and house in an instant for new infrastructure without the right to go to court...
@@zelemas3062 It is exactly because of the opportunities for people to object they should get their fingers out and go to work.

The tunnel elements are of reinforced concrete. They are submerged in a ditch and covered by 10 or so meters of rock and rubble. An anchor dragged by a ship won't work. If someone wants to attack this tunnel there will be both more effective and simpler ways.
I had a response here but it has magically disappeared. In short. Tunnel segments are of thick reinforced concrete, buried in a 20 meter deep ditch covered by 10 or so meters of rock and rubble. Can't hurt that with an anchor. Cheaper and more effective ways of sabotaging the tunnel exists. Also, minor fact correction: The baltic opto-cables where likely broken by dragging an anchor. The gas pipelines where likely blown up with explosives.

Uhhh, there are many tunnels that employ the same air-management technique and those go underwater as well. I'm not sure what the issue is.
@TheRailwayDrone not under water and air tight, champion
@@TecraTube Umm, Just as cars have to enter a tunnel on both ends, so does the air. Let's think about this for a second. You really think they would come up with this type of solution if they didn't think it could work? I'll trust the engineers instead of some random person on youtube. Continue your fight though.
@@TheRailwayDrone Re: "I'll trust the engineers....." granted that your thought process is valid. Hover, engineers are not always the decision makers.
Recalling a report years ago by a Consultant group, the recommendation of a roadway tunnel was presented for a short, time-limited review.
Part of the tunnel proposal included:
# Cross-traffic signal that would have caused vehicle back-ups into the tunnel.
# No fan or forced-air ventilation; motor vehicles would "push air" through by their movements.
# Adjoining walkway would feature illuminated signs when carbon monoxide levels would "exceed normal" level (Woe to motorists or wheelchair users who have a medical condition!).
# No mention of emergency pump system to de-water since location is near sea level.
After a final public hearing at the Convention Center, a bascule bridge design was decided upon and approved. It was claimed by some that the choice taken was mainly financial since a bridge structure cost less than a tunnel
Again: There are many tunnels using fans like that. And the tunnels under water are just as airtight as the ones under land. I.e. not. And there are already other tunnels under water using fans for exactly the purpose of ventilating bad air out and fresh air in.
On the subject of these fans, the engineers are definitively the decision makers.
Your "air tight" amply demonstrated your level of expertise. But as others said - do continue your fight.
The World's Longest Underwater Connection at 18km❓
The under sea tunnel at Calais is 35km❗
The longest combined road and railway underwater connection. You are not able to drive a car through the Chunnel. You have to load it onto a train. Thus the Chunnel is considered a railway connection only. Two different beasts. The Chunnel had a whole lot of extra challenges and had to choose a rail-only solution for a lot of reasons.
However, the solution used for Femern (Danish spelling) could perhaps be used for the Irish Sea? Going from Scotland near Portslogan to Whitehead in Northern Ireland? I know that there is a problem with the area having been used to dump unused bombs and ammo, but that could be cleaned up.
@@JKristofferNielsen "combined road and railway"
That's not what the title says❗
I am sure Denmark will finish this project as planned BUT I note that the German´s, that do not contribute one dime to the connection, have promised to build and connect train lines in Germany to the tunnel have not even begun. The Danes began building the tunnel with this promise in mind as it will be a crucial part of the repayment of the invested capital. Right now Germany have a higher unemployment than for a longer time. Maybe time, Germany, to work on materialising the trainlines so the tunnel actually can function as planned. Honestly, Denmark are building a tunnel with designated tunnels for trains and might risk they will be useless, because Germany might not be ready to harvest the free orange that landed in their turban. What´s going on German?
Well, DB is planning to get everything built up to 2029, which would be fast if you see how long it could take in Germany to become able to start legaly because of all the regulations and possibilities for the public to go to court against the things the developers planned. If you look to the danish side, litaraly no one lives where the laying the tracks to Sundby, on the german side there are 88 kilometers to built crossing through several cities and villages - and every neighbour of the new track can oppose the plans and at least go to court. That takes time, much time and is a pain in the ass - but we're not in Japan, where the goverment can take your ground and house in an instant for new infrastructure without the right to go to court...
@@zelemas3062 It is exactly because of the opportunities for people to object they should get their fingers out and go to work. Germany did not promise to start legislation work when tunnel were built but to have a functioning rail line ready at that time. It should not come as a surprise for German politicians how the legal rights are for the German´s affected.
@@zelemas3062 LOL. "someone" did not like my response, so comment can only be read if you go the "sort by" function of comments above and select "Newest first" instead of the default "Top comments".
I have not yet heard one word about the security plan if fire breaks out or a serious water leak occurs.
18Km The World's Longest tunnel? According to info readily available on the internet the Japanese Seikan tunnel is 53.85Km and the Channel Tunnel is 50.46Km
It will be the longest submerged tunnel in the world.
@@akyhne Not what the headline stated.
@@BJHolloway1Well, it says at the beginning “the longest underwater road and rail connection”. Which is true in the sense that it will be the longest combined road and rail tunnel (below the sea). But there aren’t that many combined tunnels anyway, at least with any significant lengths.
It will be the longest tunnel in the Fehmarn belt! 😅
@@micke3035 It's a record breaking tunnel, no matter what you say.

Till some ship drags an anchor over it and sabatoge like they did with the cables and gas lines...
Oh, Debbie.
The tunnel elements are of reinforced concrete. They are submerged in a ditch and covered by 10 or so meters of rock and rubble. An anchor dragged by a ship won't work. If someone wants to attack this tunnel there will be both more effective and simpler ways.
I had a response here but it has magically disappeared. In short. Tunnel segments are of thick reinforced concrete, buried in a 20 meter deep ditch covered by 10 or so meters of rock and rubble. Can't hurt that with an anchor. Cheaper and more effective ways of sabotaging the tunnel exists.
Also, minor fact correction: The baltic opto-cables where likely broken by dragging an anchor. The gas pipelines where likely blown up with explosives.
That ship will get serious damages if it try to sabotage with an ankar.
Someone didn't watch 6:56 carefully. Or doesn't know how anchors work.
the impossible budget
