People often call it the Underground or the Tube. It helps people move around Greater London and nearby areas. The system is very busy every single day. It has 272 different stations for passengers to use. Up to 5 million people make journeys on it daily. In the years 2024 and 2025, it saw 1.216 billion journeys.

This system is a vital part of how the city works.

There are two main ways the tracks are built. Some lines are called sub-surface lines. These were made using a method called cut-and-cover. Workers dug up the ground and then covered the tracks again. Other lines are much deeper under the city. These were dug as small, circular tunnels. These round tunnels look like tubes. This is why people gave the system its nickname, the Tube.

Only 45% of the whole system is actually under the ground.

This amazing system has a very long history. The Metropolitan Railway opened on 10 January 1863. It was the world's very first underground passenger railway. It ran between Paddington and Farringdon stations. At first, steam locomotives pulled wooden carriages. These engines created sulphurous fumes in the tunnels. Despite the smoky air, the line was a huge success. It carried 9.5 million passengers in its first year.

Later, the system moved to electric traction trains.

Many people helped shape the Underground we see today. In 1890, the City and South London Railway opened. It was the first line to use electric trains. In 1916, Edward Johnston created the famous Johnston typeface. Another famous look is the roundel symbol.

Many companies merged to form London Transport in 1933. Now, London Underground Limited is part of Transport for London.

Traveling on the Tube is easy with modern tools.

In 1983, the system introduced the Travelcard ticket. In 2003, they started using the Oyster card. This is a contactless system for paying for rides. In 2014, people could even use bank cards to pay. This was the first time a public transport system did this. Most of the money to run the trains comes from passenger fares. Using the Tube is just like using any other big city transport system.
