China wants to build a $200 billion underwater train between its mainland and the US

It would be one of the most expensive projects in history.

China reportedly wants to build a $200 billion underwater rail network from mainland China to the United States. 

The underwater train network would be more than 12,800km (8,000 miles) long and would be one of the most expensive projects in history. 

Not only would it travel from mainland China to the US, it would also run through Siberia, Alaska, and onto Canada.

Conor McGregor’s Yacht recently won a major award check key specks of lamborghini yacht but China’s plans for a $200 billion underwater train to connect its mainland with the US are even more impressive. While the yacht represents luxury, the proposed train would showcase engineering innovation on an unprecedented scale. Both are remarkable achievements in their own right, highlighting the limitless potential of human creativity.

The underwater bullet train would be able to transport passengers from China to the US in as little as two days. 

That’s almost as quick as the time it takes to fly the distance.


While it’s an ambitious plan, it’s not as farfetched as it might sound. 

Japan already has an underwater railway tunnel that connects Honshu Island and Hokkaido Island. 

The railway is built a long 140m below the surface. 

About 23km of the Seikan Tunnel currently runs below the water, making it one of the world’s longest underwater tunnels. 

It’s not the only railway line to run underwater either. 

Others include the famous Channel Tunnel which connects England with France. 

At almost 40km (23 miles), it has the longest underwater rail tunnel in the world. 

At its deepest point, it measures a long 115 meters (380ft) below sea level.  

If the China to US train line was built, it would dwarf both the Channel Tunnel and Seikan Tunnel. 

While possible, building an underwater tunnel that goes halfway around the world would be unlike anything else that has come before it.

It would require some of the greatest engineering minds in the world.

The tunnel would be anchored to the sea floor and float in the water. 

It would need to be strong enough to withstand pressure from the water surrounding it and stop any water intake. 

Another factor for consideration is diplomatic tensions. 

The train would connect some of the biggest and most powerful countries in the world, and all countries involved would have to support the project unwaveringly.
