Alexanderplatz Train Station:
The History of Berlin's Most Important Transport Hub
When was Alexanderplatz Train Station built?
Alexanderplatz Train Station opened in 1882 as part of the Berlin Stadtbahn.
Built on the former Königsgraben (King's Moat), it grew into one of Berlin's most important train stations within just a few decades.
Why is Alexanderplatz Train Station so important?
For more than 140 years, Alexanderplatz Train Station has connected Berlin's most important transport routes. Few places show as clearly how Berlin has evolved from a rapidly growing industrial city into the vibrant capital it is today.

Alright, friends,
I honestly think there's no place I've been to more often in my life than Alexanderplatz.
Not because I think it's especially beautiful, but because it's been my most important transport hub for years.
My gym is at Alexanderplatz, my best friend works here, and almost every time I head home, I change to the M4 tram here.
Then there's my own connection to this place. I grew up near Warschauer Straße, went to school at Frankfurter Tor, my grandma Jutta lived at Weberwiese, and Alexa shopping centre used to be our meeting spot.
I guess every Berliner spent part of their teenage years hanging around a shopping mall somewhere. For us, it was Alexa.
Maybe that's why I still notice how differently people see Alexanderplatz.
For many tourists, this is where Berlin begins.
For many Berliners, it's simply where they change trains.
But there's far more to this station than escalators, fast food and crowds. Almost without you noticing, its history tells the story of Berlin itself.
Why was Alexanderplatz Train Station built in the first place?
Alexanderplatz Train Station was built during the Industrial Revolution, when Berlin was growing rapidly and needed an efficient east-west rail connection. With the construction of the Berlin Stadtbahn, Alexanderplatz became one of the capital's central transport hubs.
If you stand on the platforms today, it's hard to imagine that this was once the site of a defensive moat.
More specifically, the Königsgraben (King's Moat), part of Berlin's old fortifications, once ran through this exact spot. After the city's defences lost their military purpose, the moat was filled in. The Berlin Stadtbahn was later built on top of it, followed by Alexanderplatz Train Station.
The station was actually supposed to have a different name. Early plans referred to it as Königsbrücke Station, but shortly before it opened, the decision was made to call it Alexanderplatz Train Station instead.
Looking back, that was the right choice.
Even then, Alexanderplatz was rapidly becoming the main transport hub of eastern Berlin's city centre.
Berlin is growing – and needs a new railway
By the end of the 19th century, Berlin was growing at an incredible pace.
Factories, residential buildings and new jobs were appearing everywhere. Thousands of people moved to the capital every year. Horse-drawn carriages and the city's existing streets could no longer cope with that kind of growth.
Berlin already had several major terminal stations, but they were all located on the outskirts of the city. Anyone travelling across Berlin had to make inconvenient transfers or cover long distances.
The solution was revolutionary:
A railway would run straight through the heart of Berlin, connecting the city's existing train stations.
That's how the Berlin Stadtbahn came into being.
It linked the former Schlesischer Bahnhof (now Ostbahnhof) with Charlottenburg and, later, today's Westkreuz. For the first time, passengers could travel across Berlin from east to west without long detours.
Alexanderplatz Train Station was built right along this new railway line.
A train station for a growing world city
The station was built between 1881 and 1882 based on plans by architect Johann Eduard Jacobsthal.
By the standards of the time, it was remarkably ambitious.
Its platform hall stretched around 164 metres (538 feet), covering four tracks beneath a massive steel structure. Beneath the railway, the brick viaduct arches housed operational facilities, storage rooms and, later, numerous shops – a concept that still defines the station today.
The first suburban trains stopped here on 7 February 1882.
Long-distance trains followed just a few months later.
The station's impressive size was no coincidence. Even back then, Alexanderplatz was already one of Berlin's most important transport hubs. Major roads converged here, markets and market halls attracted thousands of visitors every day, and the area around the square developed into one of Berlin's leading commercial districts.
Today, around 150,000 people change trains here every day.
Back then, however, no one could have imagined just how important this station would one day become.
What many people don't know: This was once Berlin's darkest train station
In the 1920s, Alexanderplatz Train Station was known as the darkest station in Berlin. Smoke and soot from steam locomotives had heavily damaged and blackened the steel roof structure.
With every passing train, more soot, smoke and moisture built up beneath the station roof.
During the First World War, there was little money available for major maintenance, so the structure continued to deteriorate. The steel beams began to rust, and the station grew darker and darker.
Eventually, it earned the reputation of being Berlin's darkest train station.
Between 1925 and 1926, the Deutsche Reichsbahn decided to almost completely rebuild the platform hall.
What's remarkable is that train services continued almost without interruption throughout the construction work.
Although the new hall followed the original design, it featured much larger windows. As a result, far more daylight reached the platforms – a difference passengers noticed immediately.
From steam trains to the Berlin S-Bahn
The 1920s transformed Alexanderplatz Train Station.
It wasn't just the station hall that was rebuilt.
At the same time, Berlin began replacing steam-powered local trains with electric railcars.
On 11 June 1928, the era of the Berlin S-Bahn officially began at Alexanderplatz. At first, steam locomotives and electric trains still operated side by side. But over time, steam trains disappeared from the city entirely.
The electrification made the station faster, more efficient and better equipped for the growing number of passengers.
Around the same time, new ticket halls and waiting rooms were built, along with the station's first direct connection to the newly developing U-Bahn — complete with escalators. For its time, this was cutting-edge infrastructure.
But beneath Alexanderplatz, another project was only just beginning — one that would turn the station into one of Europe's most remarkable transport hubs.
A transport marvel beneath Alexanderplatz
With the construction of the U-Bahn, Alexanderplatz Train Station became one of Europe's most advanced transport hubs.
Between 1913 and 1930, three interconnected U-Bahn stations were built on multiple levels – a concept that was far ahead of its time.
While more and more people were travelling above ground on the Stadtbahn, another major construction project was already taking shape beneath Alexanderplatz.
Work on the first U-Bahn station began in 1910.
Architect Alfred Grenander, whose designs still define many of Berlin's U-Bahn stations today, created the platform for today's U2 line. When it opened on 1 July 1913, planners were already thinking ahead. Beneath the station, they even built a structural shell for a future line towards Friedrichshain, despite there being no immediate plans to construct it.
A few years later, today's U8 and U5 lines followed.
By 1930, a vast underground interchange had been completed beneath Alexanderplatz in the shape of a giant "H". The U2 runs along one side, the U8 along the other, while the U5 crosses beneath them. Spacious underground passageways connect all three platforms.
Today, that feels completely normal.
Back then, however, it was a remarkable engineering achievement.
The underground shopping arcade was one of the first of its kind. It not only connected the platforms but also gave passengers direct access to the department stores surrounding Alexanderplatz.
Whenever I walk through those passageways today, I often think about the millions of people who use them every day without realising just how innovative this station was almost a century ago.
The Second World War leaves deep scars
Bombing raids and the Battle of Berlin left Alexanderplatz Train Station heavily damaged. It took several months after the war ended before the first trains were able to run again.
Like few other transport hubs in the city, Alexanderplatz Train Station was hit hard during the Second World War.
Bombs destroyed large sections of the station hall, all of the glass roof panels were blown out, and several of the steel support beams had to be removed. When the Battle of Berlin began, rail services eventually came to a complete standstill.
Historic photographs show a station that's almost unrecognisable.
Surrounded by rubble, twisted steel beams and destroyed tracks, little remained of the modern transport hub that had existed before the war.
Yet by 4 November 1945, the first S-Bahn trains were already running through Alexanderplatz again.
The full reconstruction continued until 1951.
Berlin was moving again – even if it was now under a completely different political system.
Why was Alexanderplatz Train Station completely rebuilt during the GDR?
The GDR wanted to turn Alexanderplatz into the representative centre of East Berlin. That's why the station was redesigned to match the new socialist vision of the city.
My grandma Jutta still tells stories about Alexanderplatz from long before the Berlin TV Tower or the World Clock existed.
When you walk across the square today, that's hard to imagine.
But until the 1960s, Alexanderplatz looked completely different.
After the construction of the Berlin Wall, the GDR government decided to redesign the entire square. Alexanderplatz was meant to showcase what the socialist capital was capable of.
The station was rebuilt as well.
Large glass façades were added to both sides, the lower section was clad in granite, and a wide pedestrian passage was created through the building. At the same time, the platforms were modernised for the expanding S-Bahn network.
With the opening of the World Clock and the Berlin TV Tower in the late 1960s, the new Alexanderplatz was finally complete.
If you'd like to know why these two landmarks are still among Berlin's most iconic symbols today, you'll find dedicated blogs about the Berlin TV Tower and the World Clock here.
The Ghost Station beneath Alexanderplatz
After the Berlin Wall was built, the platform used by today's U8 line was closed. For years, trains from West Berlin passed through the station without stopping – which is why it became known as a ghost station.
For me, this is probably the most fascinating story of the entire station.
Imagine boarding a U-Bahn train as usual.
The train enters a station.
The lights grow dimmer.
A few border guards are standing on the platform.
No one gets on.
No one gets off.
A few seconds later, the station disappears back into the tunnel.
That's exactly how many passengers experienced Alexanderplatz on today's U8 line.
After the Berlin Wall was built on 13 August 1961, the platform was completely cut off from the rest of the station. The entrances were bricked up and carefully covered with matching tiles, so hardly anyone realised there was still a platform hidden behind them.
While thousands of people changed daily between the S-Bahn and the U5 just above, trains continued to pass only a few metres below.
Without stopping.
Without passengers.
For almost three decades.
I can hardly think of another place in Berlin where the division of the city feels more tangible than it does here.
Reunification and a new chapter for the station
The fall of the Berlin Wall marked another turning point for Alexanderplatz Train Station.
In 1990, the U8 once again began stopping regularly at Alexanderplatz.
For many people in East Berlin, it was a surreal moment.
Suddenly, there was a platform they hadn't even known existed for decades.
During the 1990s, the entire Stadtbahn was extensively restored.
Many GDR-era alterations were removed, revealing the original brick viaduct arches once again. Large glass façades, new shops and today's station hall were all created during this redevelopment.
Since 1998, the S-Bahn has once again used only its original platform, while the western platform is now served by regional trains.
Alexanderplatz Train Station today – and why it's so important
Today, Alexanderplatz Train Station brings together the S-Bahn, regional trains, U-Bahn, trams and buses in one place, making it one of Germany's most important transport interchanges.
During my time as a concierge, I've probably explained to thousands of guests how to get to Alexanderplatz.
Most of them were heading to the Berlin TV Tower, Museum Island, or simply wanted to explore Berlin's city centre.
And honestly, Alexanderplatz was almost always the best place to start.
Today, the station connects almost all of eastern Berlin with the city centre.
From here, you can reach the East Side Gallery, Oberbaum Bridge, Volkspark Friedrichshain, or even the Gardens of the World and the North Side Gallery without changing trains.
With around 150,000 passengers every day, Alexanderplatz Train Station is one of the busiest train stations in Germany.
For many tourists, this is where Berlin begins.
For most Berliners, it's simply where they change trains.
The future of Alexanderplatz Train Station
Alexanderplatz Train Station is changing once again.
Since 2026, the station has been undergoing its biggest renovation in decades.
The entire ground floor is expected to be technically modernised by the end of 2029.
The project includes upgrades to the fire protection system, heating and air conditioning, power supply, lighting, lifts, escalators and the station's entire technical infrastructure. During the construction work, almost all shops have had to close.
Train services, however, continue to operate for the most part.
From the outside, the station will hardly change.
That's because the entire station complex is protected as a historic monument.
Final thoughts on Alexanderplatz Train Station
You might be wondering.
After all, this platform is called NO TOURiST INFO.
So why write a blog about Alexanderplatz?
Because we're not interested in typical tourist attractions.
We're interested in places that explain Berlin. And few places tell the story of this city as well as Alexanderplatz Train Station.
This is where industrialisation, two world wars, the division of Berlin, reunification and modern-day Berlin all come together.
Today, I probably walk through this station as casually as millions of other Berliners.
And yet, sometimes I think about my grandma Jutta, who knew Alexanderplatz long before the Berlin TV Tower and the World Clock existed.
I think about my teenage years, when we used to hang out at Alexa after school.
Or about the countless guests I helped find their way to Alexanderplatz.
And that's when you realise that, for more than 140 years, this station has always served the same purpose.
It brings people together.
And sends them on their way.
Berlin isn't a tourist attraction. Berlin is a city.

Take care 🖤
