How Deep Is the Madrid Metro?

By Alice Nichols

The Madrid Metro is one of the most extensive underground transportation systems in the world, with over 300 stations spread across a network of 12 lines. It’s a popular mode of transportation for locals and tourists alike, but have you ever wondered how deep the metro actually goes? In this article, we’ll explore just how deep the Madrid Metro is, and what factors influence its depth.

The Basics

Firstly, let’s start with some basics. The Madrid Metro has different depths depending on the station and line, but on average it is around 15-20 meters deep.

This is equivalent to about five to six stories underground. However, some stations are much deeper than others.

Factors Influencing Depth

The depth of each station depends on several factors. One of the most important factors is geology. Madrid sits on a bedrock composed of granite and metamorphic rocks that can make drilling difficult and expensive.

Another factor is the city’s architecture and infrastructure. Due to the historical value of many buildings in Madrid, it can be challenging to dig deep underground without damaging these structures. Additionally, some areas may have utilities or other infrastructure that could interfere with metro construction.

Deepest Stations

Now let’s take a look at some of the deepest stations on the Madrid Metro.

  • Gran Vía Station: Located on Line 1 and Line 5, Gran Vía Station is one of the deepest stations at approximately 28 meters below ground level.
  • Sol Station: Sol Station is located in central Madrid and serves as one of the busiest stations in the city; it’s also one of the deepest at around 30 meters below street level.
  • Tirso de Molina Station: Tirso de Molina Station on Line 1 is another deep station, with a depth of around 32 meters below ground level.

Conclusion

The depth of the Madrid Metro varies depending on several factors, including geological conditions, infrastructure constraints, and local architecture. While the average depth of the metro is around 15-20 meters, some stations are much deeper than others. The Gran Vía Station, Sol Station, and Tirso de Molina Station are among the deepest stations on the Madrid Metro.
