The largest shunting station in Europe
A gigantic network of rails: We take a look behind the scenes of Europe's largest shunting station.
The longest suspension bridge in Europe
A new suspension bridge has just opened in Reutte in Tyrol. With over 70 tons and 400 meters, it is currently the longest suspension bridge in Europe. We show how this mega project came about and why a small toy helicopter played such an important role during construction.
World's Biggest Intersection
This is the biggest and craziest intersection in the world: 5 levels, 20 junctions. Navigating your car through it or crossing as a pedestrian can be quite the adventure, and dangerous to boot. We take a look at the mechanization of this intersection and how it all works!

00:01It's easy to run out of superlatives here.
00:04Europe's largest marshaling yard is also where the longest train in Germany,
00:09measuring an impressive 2,700 feet, is put together.
00:13The station itself is a gigantic maze of tracks totaling 160 miles.
00:19We want to take a closer look at this and have traveled to Maschen, 15 miles south of Hamburg.
00:25Standing at ground level, we can only guess the incredible dimensions of the second largest marshaling yard in the world.
00:33Railway tracks seem to stretch as far as the eye can see in all directions.
00:41Only when airborne do we get an idea of this gigantic size.
00:46One million wagons arrive here every year.
00:49That makes several hundred trains a day.
00:52They all have to be uncoupled, sorted out and reassembled.
00:55Like a gigantic puzzle, especially when it comes to the longest train in Germany.
01:02It transports food, industrial parts, cars and petrol to Scandinavia.
01:07To make this happen, the schedule is very tight.
01:10The train must be ready in a few hours.
01:12But how is that done?
01:1340 wagons with a length of 2,700 feet.
01:19We accompany the berth of Germany's longest train.
01:236 o'clock in the morning.
01:25A train is just arriving from Cologne, delivering the final wagons for our record-breaking train.
01:31Now the employees in Maschen have exactly 6 hours to solve this XXL puzzle on rails.
01:37And we are allowed to watch them do it.
01:39The switcher gets things going.
01:42Eric Hilgert is one of them.
01:44He uncouples the train, separating the individual wagons and breaking the train down to individual units.
01:50A really tough job.
01:52The longest I have ever had was 43 wagons.
01:59Some couplings weigh up to 35 kilos.
02:04And if you have to lift up to 20 to 30 of them, you can definitely do some damage to your back.
02:11The switcher has to release the heavy iron couplings that hold the wagons together by hand.
02:19This gets even more difficult if the train driver stops the train the wrong way.
02:25If the connections are under tension, they are particularly difficult to release.
02:29The technical term for this is elongated.
02:32The train is elongated when it is pulled an inch or two apart.
02:37The screw coupling then becomes so tight that you can't get it to move.
02:41I always complain to the drivers when the train is elongated.
02:44At 2300 feet, always having to wait just eats up time.
02:48And the switcher doesn't have much time.
02:51Now there are only four hours left until departure.
02:54Time for the shunting driver to get involved.
02:57He must now move the detached wagons.
03:00And Wolfgang Paul does this with the necessary calmness.
03:04I've been here 37 years, so it's probably not that special anymore.
03:10But that's the way it is.
03:11I mean, if it was any smaller, I'd be riding this track right now.
03:15You can't really see the size when you sat here on the locomotive.
03:19Only when airborne, the gigantic dimensions can be seen.
03:25The task begins.
03:27The shunting locomotive pushes the loose wagons to where they are distributed.
03:31That, however, is done by a computer, which controls the speed.
03:36Wolfgang Paul's only task is stopping the train in an emergency.
03:40I'm responsible for the emergency stop foot switch.
03:43So if I fall asleep or become unconscious or can't see what's happening,
03:46then the locomotive stops after a certain time.
03:49Wolfgang, come in, please.
03:5141 to the train.
03:54All right, we're starting.
03:58At walking speed, the shunting locomotive pushes the wagons along the track.
04:03The shunter can't see what's going on at the front.
04:06A third person is responsible for this.
04:13My two eyes have to be enough.
04:15No, the watchman stands there at the front.
04:17The colleague who checks the train keeps an eye on the front as well.
04:20That's what he's there for, because I can't see everything here.
04:23When I say I'm starting, then he has to say if something's not right,
04:27or shout stop or something, if someone's in the way, whatever.
04:30But that hasn't really happened up to now.
04:33Four and more.
04:34But it's not yet before.
04:361,600 tons are now moving towards the so-called hump.
04:41Due to the height difference of 10 feet, the railway wagons roll onto one of the 48 shunting tracks using their own weight.
04:49The computer controls the speed using a retarder brake.
04:52High-speed switches ensure that the wagons end up on the right track.
04:56There are now only three hours left.
05:02And this is how the puzzle works.
05:04The split-up train from Cologne has a total of 32 wagons.
05:08The yellow ones have to go to LĂĽbeck.
05:13The pink ones to Hamburg Harbor.
05:15And the green ones belong to our record train.
05:18Here in Maschen, these wagons are now sorted like toy trains.
05:22All wagons for the record train are moved to track 2036,
05:26where the remaining wagons for the longest train in Germany, number 44724 to Denmark, are already waiting.
05:33Watching over the supersized puzzle is the so-called humpmaster.
05:40It has to be ready in just under two hours.
05:43From his tower, Christian Möller monitors the rolling.
05:47In an emergency, he can take control away from the computer immediately.
05:52This is for all emergencies.
05:55For locomotives, if anything goes wrong with it, an accident or something,
05:59then I can make an emergency stop here.
06:02Or for all the conveyors.
06:04This is the emergency stop here to stop people getting hurt.
06:08Christian Möller has been working for the railway for 40 years.
06:12For 30 years, he has been the humpmaster in Maschen.
06:15He loves the variety and the challenges of the job at Europe's largest marshalling yard.
06:23At a little station, there are two trains a day.
06:26Whereas here, there's one train after the other.
06:28And particularly from the port, they just keep coming.
06:31The port of Hamburg is the reason why the largest marshalling yard in Europe was built here.
06:37A gigantic amount of goods and containers arrive by ship every day.
06:41This is why there used to be five marshalling yards in Hamburg.
06:48The train formation was therefore distributed over various locations and this took considerably longer.
06:54Because even then, 2,500 wagons had to be sorted every day.
06:59Unthinkable for the longest train in Germany.
07:02Train number 44727 is almost finished.
07:05Pulled by this locomotive, it is scheduled to leave for Scandinavia in one hour.
07:11The final check by the so-called wagon technician is the last remaining step before departure.
07:16And Holger Lang has found something.
07:18This wagon's up for inspection.
07:21You can see here, it was last checked on the 5th of March 2009.
07:25The wagons are all inspected.
07:27Wearing parts are replaced.
07:29It's like a minor road-worthiness test.
07:32This wagon can make one last trip, then it has to go into the repair workshop.
07:41The wagon technician checks that the load is properly stowed and secured, that all doors are closed and not damaged.
07:48What's contained inside the rail wagons is something Holger Lang does not normally know.
07:53We don't have to look inside unless we've been specially instructed.
07:59Or if the doors bulge and there's something pressing against them.
08:03Sometimes there's some impact damage, it's been hit by a forklift or something.
08:06We just have to make sure the doors are properly locked.
08:10Finally, he checks if all brakes are released.
08:13The method he uses is rather unusual.
08:18We have brake pads here.
08:20This is the brake shoe.
08:21When the brakes are applied, they sound dull.
08:24Can you hear it?
08:25When the brakes are loose afterwards, they sound bright.
08:28Let's take a look here.
08:30This should be released.
08:31Then, it sounds like this when they're off.
08:35You can hear if the brakes are off or on.
08:40Everything is fine.
08:42The longest train in Germany can set off for Denmark on time.
08:462,700 feet, more than 40 wagons are slowly set in motion.
08:51And that happens 12 times a week.
08:54The train runs with a special permission.
08:56On all other routes, the maximum permitted length is 2,400 feet.
09:01The XXL train takes three hours to cover 130 miles.
09:06The 2,000 tons are not allowed to move faster than 60 miles per hour.
09:11Nevertheless, the train has a braking distance of almost 3,200 feet.
09:16The longest train in Germany, one of about 600 trains departing from the largest marshaling yard in Europe every week.
09:25This accounts for over 3,000 wagons a day rolling over 170 miles of rails spread over an area the size of 380 soccer fields.
09:36That is the secret behind this impressive aerial photograph.
09:48This construction project is breaking records.
09:51With a $2 million price tag, a weight of 70 tons and a total length of 1,318 feet, its success is literally hanging by a thread.
10:03The bridges engineer Theo and his son Kevin are trying to achieve the impossible.
10:08They want to build Europe's longest suspension bridge with the help of a drone.
10:13There is little time until the opening ceremony and working at 328 feet up in the air is extremely dangerous.
10:20Your life basically depends on someone else's actions.
10:25You don't have to worry about it.
10:26But you keep your hands still still close, that's not necessary.
10:30Are they going to be successful with this bold idea?
10:40It's 6am on an early September day in Reuter in Tyrol, Austria.
10:45Europe's longest suspension bridge will soon stretch above this valley.
10:4921-year-old Kevin Lauber is one of the people in charge of the construction.
10:54He arrived here from Switzerland yesterday and spent the night in his car right next to the construction side.
11:00The deadlines are tight and a lot of things could go wrong.
11:04We've made all the necessary preparations, but there's no ultimate guarantee.
11:08There's no guarantee.
11:12Kevin has been preparing for this moment for months.
11:17Together with his father, he wants to lay the foundation for a multi-million dollar construction project using only a drone and a thin wire.
11:31We've never used a drone for a project of this size before.
11:35The last time we built a large-scale suspension bridge, we worked with a helicopter.
11:42The weather conditions are far from ideal.
11:48Using the drone in the thick fog could be difficult.
11:51It affects the GPS of the quadcopters and that makes it harder to navigate.
11:56You'd have to control the drone manually, but that's tricky, especially when it's carrying a load.
12:02They want to use the drone to install the 1,312 feet long pilot cable for the bridge.
12:13However, they've never worked with a drone over such a long distance before.
12:16It all starts with a thin wire.
12:19The drone carries the wire across the valley, connecting what will later become the two ends of the bridge.
12:26We'll find out more about the construction process in a little while.
12:31Kevin is extremely focused.
12:32The expectations are very high. If you can't keep a cool head, you're not the right person for this kind of job.
12:46Kevin and his father Theo are working on opposite sides of the valley today.
12:57Kevin sets up the drone and attaches the thin pilot cable.
13:01At the end of the day, the project's success rests on his shoulders.
13:05It's still very foggy and his father is basically flying blind.
13:08He's going to help him navigate via radio.
13:15The slightest gust of wind could cause the wire to snap.
13:19Martin Cathrine is the technical site manager and initiator of the project.
13:24He always believed in the idea of the record-breaking bridge and managed to find four private investors for the $1.7 million project.
13:32Well, I did my research. Some people actually don't believe that it's possible.
13:39I hope we're in for a positive surprise.
13:43Kevin and Theo decide to proceed despite the grim weather conditions.
13:48Efficient communication between father and son is crucial for the success of the drone maneuver.
13:53You'll have to fly at least 13 feet above the treetops.
13:58Once the drone is in the air, Theo has to fully rely on his son.
14:04The drone is about to take off now.
14:07I'll be an extra set of eyes for my dad and help navigate the quadcopter.
14:12He has to be able to trust me.
14:15Precision is very important for this project.
14:17OK, stop.
14:18OK, Achtung.
14:19Let me tell you when he goes.
14:20I can't see anything. Do you have it under control?
14:24Can you see something through the camera?
14:40No, I can't.
14:42OK, but is the GPS working?
14:44I don't know.
14:47The success of the project is literally hanging by a threat now.
14:51The drone is approaching its destination at 12.5 miles per hour.
14:55It takes a skillful drone pilot to do that.
14:58Just a tad too fast and the wire might snap.
15:06And then the wire is suddenly gone.
15:08This is exactly what we were afraid of.
15:12The wire got stuck on a mast.
15:14I hope we'll manage to get it loose.
15:16What am I supposed to do now?
15:18Should I just wait until you give me a heads up?
15:21Kevin finds out that the drone arrived on the other side without the wire.
15:25It has snapped.
15:26He can't do anything but wait.
15:28The team on the other side is discussing how to proceed.
15:38We've already dismissed Plan B, contemplated Plan D and now we're discussing Plan E.
15:44It's a good thing that the alphabet has 26 letters.
15:46Theo decides to give it another try and the drone is being transported back to Kevin.
15:52Meanwhile, builders are working on a safety tunnel down in the valley.
15:56The new suspension bridge will be built over a busy highway
16:00and objects falling from the bridge could cause fatal accidents.
16:03The fog finally clears and the drone is up in the air again.
16:17This time the drone has managed to reach its destination without losing the wire.
16:30The first threat is now being used to pull over even more threats and increase the thickness.
16:36That takes almost an entire day.
16:38The result is a steel rope that is strong enough to carry the weight of a heavy bridge cable.
16:43A winch will be used to transport the suspension bridge cables across the valley.
16:48The precise alignment of those cables is important for the statics of the bridge.
16:52Only 35 days left.
17:00The suspension cables have been successfully installed and aligned.
17:04The actual construction of the bridge can finally begin.
17:07The team wants to start with the assembly of the gratings.
17:11Kevin is back at the construction side.
17:13Well, my goal for today is to at least get a little further than the highway.
17:20I think that would be very good.
17:23They have to install at least 22 gratings per day to complete the construction works before the grand opening.
17:32The gratings for the pedestrian walkway are 47 inches wide.
17:36Unfortunately, one of the most important people on the construction side isn't fully fit today.
17:42Three of us were carrying a 220 pound metal grating and it slipped from our hands.
17:50I was wearing safety boots, but it hit me higher up the foot and I broke a metatarsal bone.
17:57Kevin is trying to support his father as much as he can.
18:04He had never envisioned being a bridge builder.
18:07As a matter of fact, only seven years ago he was still terrified of heights.
18:12It always takes me about 30 minutes to get used to the height when I'm working on a new construction site.
18:20But I usually start to enjoy it after a little while.
18:23Kevin is secured to the bridge with a carabiner.
18:27Everybody is responsible for their own safety as well as that of their co-workers.
18:35You have to be able to trust your workmates completely.
18:39Trust is the prerequisite for this kind of job.
18:42Your life basically depends on somebody else's actions.
18:48Kevin is working 196 feet above the ground.
18:51He first attaches the bulky brackets to the supporting cables.
18:55They will be used for fastening and securing the bridge deck.
18:59They have to push the bracket further down so that we can attach these bars that will later hold the gratings.
19:06We have to repeat this process 120 times.
19:10The workers use a trolley to move the 13 feet long steel gratings.
19:14One person is in charge of securing the heavy grating to protect the railroad crossing and the highway right below the construction site.
19:22The men are on edge.
19:24You have to push harder. Use both hands. Don't hold on to the railings. There's no need for that.
19:29The gratings are pushed into place with hands and feet. For more flexibility, the screws won't be tightened before the construction is complete.
19:38Can you move them a little closer together?
19:48Kevin adjusts the suspension cables. They will run closer together in the middle section of the bridge.
19:53Theo checks if everything is done according to his calculations.
19:56I'm checking the alignment. The curve of the bridge wasn't quite right. So we had to make a few changes there.
20:11Only when every little detail is right will the bridge be able to hold up to 500 people, even in wind speeds of 37 miles per hour.
20:25Of course I care about the opening date. But when I'm not 100% satisfied with the project, I can't change that.
20:32I can't change that.
20:38Project supervisor Martin Cathrain visits the side daily. He's also keeping the investors in the loop. Their patience is being put to the test.
20:51I'm an eternal optimist. But to be honest, I'm approaching my limits.
20:55We've already had to increase the buffer once. Now we're hoping that the final amount won't be more than 15 to 20% higher than the estimate. So that would be 2 million dollars.
21:08Time is money and the construction workers are finally finding their groove.
21:13They manage to assemble 16 gratings a day, which equals 164 feet on the bridge deck.
21:18If Theo's calculations were accurate, all parts should fit together perfectly in the end.
21:27I can tell you the exact length of the suspension cables, but the length of the walkway is a different story.
21:34There's a certain clearance between the different parts.
21:37I've built bridges that ended up being 60 feet longer than planned.
21:42Theo and his team will have to wait until the end.
21:47to find out the exact length of the new suspension bridge.
21:54Seven days until the grand opening.
21:57After more than 10 years of planning, the last part of the bridge will finally be completed today.
22:03There's only 65 feet of the bridge deck missing.
22:06Theo and his workers have been at the construction site since sunrise.
22:10Are you nervous, Theo? There's no time to be nervous.
22:14We're about to find out if Theo's calculations were right.
22:18Meanwhile, he's on his way to the connection point.
22:2068 feet.
22:3168 feet.
22:3368 feet of the bridge deck are still missing.
22:36However, the steel gratings are just 65 feet long, too short for the gap.
22:39With the finish line so close, everybody wants to help.
22:45Even Martin Cathrine, the technical site manager, is suddenly operating the excavator.
22:51This is going to be the last part of the bridge deck.
22:54In just a few moments, we'll be able to walk across the bridge.
22:58I've waited for that moment for over two and a half years.
23:01The last 19 feet long steel grating is being transported to its destination.
23:06The last 19 feet long steel grating is being transported to its destination.
23:09The last 19 feet long steel grating is being transported to its destination.
23:13The last 19 feet long steel grating is getting the third-hand side.
23:14The four-hand side is being transported to its destination.
23:21If you stop here, with the other side is going to be the engine back.
23:22Just keep them outside and keep them out.
23:23It's the clutched burger chain.
23:25They are coming in the driving market.
23:30They made it.
23:32But what about that last gap?
23:34That wasn't part of the initial plan.
23:38We're on it.
23:40We're on it. We'll just pull the two sides together with a chain hoist and screw them in place.
23:48The two parts of the bridge deck are pulled together with simple straps.
23:53Success at last. The construction crew is overjoyed and visibly relieved.
23:58I had my doubts in the beginning, but Martin was always optimistic and put his heart and soul into this project.
24:13I couldn't be happier how it's turned out.
24:17Two members of the crew are missing from the celebration.
24:21Theo and Kevin are over on the other side of the valley.
24:24They still have a lot of work to do before the grand opening in seven days.
24:29In the evening, father and son finally walk across their bridge for the very first time.
24:34Theo is beaming with pride.
24:41My suspension bridges don't sway. They move people.
24:45Finally. After six months and 11 days, the construction is finally complete.
24:51The 1,332 feet long bridge is now, officially, Europe's longest suspension footbridge.
25:04Chongqing in China.
25:06With 36 million inhabitants and a land area as large as Austria, it's the largest city in the world.
25:15And it's the city with the most congestion in China.
25:18Commuters here take an average of 55 minutes per journey.
25:27Six hundred and seven thousand cars drive here every day.
25:31In order to relieve the traffic network, a giant new traffic junction,
25:35which connects a total of eight different directions,
25:38is currently being built in the west of the city.
25:40This is it. It looks really huge. Really high.
25:48It's got lots of different levels.
25:51To appreciate how big the intersection really is,
25:54we turn on the drone camera.
25:58Because only from the air is the size of the intersection really clear.
26:03The node point stretches across 400,000 square meters.
26:17Although this is quite large,
26:19the Frankfurt intersection, the largest junction in Germany,
26:22covers about the same area.
26:24The difference?
26:25There are many more branches in Chongqing.
26:27A total of 20, on five separate levels.
26:31Comparable to this is only the Judge Harry Pregerson crossing in Los Angeles.
26:35There are 18 branches, but on only four levels.
26:40And how do you drive on the world's largest intersection?
26:43We meet an expert to clarify this.
26:50The local driving school teacher, Don Yu,
26:52has had more customers since the construction of the intersection
26:55because the junction is a popular test area.
26:58Driving student Zhang Yang has her driving test tomorrow.
27:02Today, she's meant to prove her skills.
27:07Today, we'll drive over the complex intersection.
27:10It's also part of the test.
27:11Do you think you're up for it?
27:15I hope so.
27:17Zhang Yan has already completed 60 driving hours in city traffic.
27:22Today is her first time on the highway.
27:28I'm already nervous to drive over such a complicated intersection,
27:32especially in the test tomorrow.
27:34But if you practice more, you will drive better afterwards.
27:37The driver's license is about 700 euros in Chongqing,
27:44significantly cheaper than in Germany.
27:47However, you don't really have to drive over a highway intersection of this sort back home.
27:54Slowly, using the brake.
27:56I'm afraid of those tracks.
27:58Don't worry, focus on driving.
28:04In China, you have to pass a total of three practical exams.
28:08Zhang Yan has already taken the parking and regular city traffic tests.
28:13The highway intersection is the last one.
28:15At the next intersection, you have to be extra careful.
28:26Yes, there are many cars.
28:29Driving instructor Don Yu has to grab the steering wheel.
28:33Zhang Yan is tense.
28:34The heavy traffic scares the student.
28:42Where should I go?
28:44Go, go.
28:47And it gets worse.
28:54A full emergency stop in the middle of the highway.
28:58She would have failed in tomorrow's test.
29:00Driving instructor Don Yu manoeuvres the car from the intersection
29:04with his hand on the steering wheel.
29:19This five-story intersection is the tallest and most complicated one in China.
29:24The cars come from eight different directions.
29:26Driving on this intersection is very complicated and tough.
29:33You have to think about where you're going,
29:35which lane you're taking,
29:36whether to use your indicator lights or not.
29:39Otherwise, an accident will happen.
29:42We hope for her she'll do better in tomorrow's test.
29:49How do people work on and under the largest intersection in the world?
29:53Only 150 meters away from the intersection,
29:58there's Mr. Zhao's car repair shop.
30:03His shop has been here for the past 20 years.
30:06Since the intersection was established,
30:08the business has been doing much better
30:10because there's a lot of clientele close to the ramp.
30:13It's going fine, especially because many cars pass by.
30:22If something breaks, they come here for help.
30:24I'm happy to work next to the intersection.
30:29He's not the only one working here.
30:33Also around the intersection,
30:35there's still plenty of building going on.
30:37It's going to be even bigger.
30:39On the north side, another four-lane road is under construction.
30:44It's eventually going to connect north and south Chongqing.
30:48The construction costs around 8 million euros.
30:51The challenge?
30:52This section is located in the middle of a mountain range.
30:55This makes the work much more difficult.
31:01It's not that easy to transport the building materials here.
31:07Seven days a week, nine hours per day,
31:10they dig and level the terrain.
31:14The name of the new road, Fumin.
31:16That means the convenience of the people.
31:19The giant crossing is great for the motorists.
31:24But what about those who live here?
31:29We see people running over the highway again and again.
31:33Unthinkable in Germany.
31:36Why are you walking here?
31:39It's illegal, but people live everywhere around here.
31:44There are no pedestrian paths,
31:46but a lot of homes.
31:49And how do people live around the largest intersection in the world?
31:57Only 200 meters away from the giant intersection,
32:00Ms. Jung has her apartment.
32:03Together with her husband, Ji Chang,
32:05she has lived right next to the intersection for seven years.
32:09Ji Chang worked as a graphic artist for 40 years
32:12and bought his own house with his savings.
32:15Today, however,
32:17they live in this 55 square meter apartment on the 28th floor.
32:22That's relatively normal for China.
32:26But why did they swap their house for the apartment
32:29right next to the intersection?
32:30Our house was there in the middle of the construction side area,
32:38right there where the highway was to go.
32:41Moving here was a good option for us.
32:43When the excavators arrived,
32:49the Jungs accepted the government's offer
32:51and moved into the replacement apartment.
32:54The construction work on the intersection has lasted seven years.
32:58In 2019, it should be ready.
33:00This also means construction noise seven days a week.
33:10We measured 80 decibels, as loud as a moving truck.
33:17Yes, but the noise is not that big of a deal.
33:20The intersection has made our life easier
33:22and the neighborhood is nicer here.
33:24In fact, the drive to the city center
33:30takes only half the time nowadays.
33:33Mr. Yun has to visit his sick father every day.
33:37For this, it's enough to drive along
33:38the entire traffic junction on his tuk-tuk.
33:41For him, the intersection is therefore a good thing.
33:47It used to take over an hour.
33:49Today, it only took me about 40 minutes.
33:51So if something urgent happens,
33:54I can get to my father quickly.
33:57To make sure the intersection isn't just practical,
34:00but beautiful as well,
34:02dozens of gardeners work under the junction
34:04to turn the brown earth into a green oasis.
34:12It's heavy work,
34:13since the rocky ground offers plenty of resistance.
34:16But it's not just about beautifying the intersection.
34:19I think it's good to plant flowers here.
34:25That improves the air quality.
34:2820,000 square meters of green
34:31will reduce air pollution in the future.
34:34Even if many more plants are needed
34:36for better air quality,
34:38the people of Chongqing
34:39benefit from the world's largest intersection.
34:42side of the distance.
34:44Education.
34:49Education.
34:54Education.
34:55Education.
