The Milan Metro is a huge train system in Milan, Italy.
The system works using different ways to provide electricity to the trains. Lines 2 and 3 use overhead lines to give power. These lines use 1500 V DC of electricity. Line 1 uses a fourth rail system with 750 V DC. Lines 4 and 5 use a third rail system. 
Planning for the metro began a long time ago. People first drew up plans in 1914 and 1925. These ideas came from looking at cities like London and Paris. A big project for seven lines was planned in 1938. However, World War II and a lack of money stopped the work.
The first part of the metro opened on November 1, 1964.
Traveling on the metro is very easy for passengers.
The Milan Metro is a massive rapid transit system located in Milan, Italy.
The metro uses several different methods to provide electricity to its trains. This is necessary because different lines were built at different times using different technologies. Lines 2 and 3 rely on overhead lines to supply 1500 V DC of electric current. Line 1 is slightly different. It primarily uses a fourth rail system with 750 V DC. Interestingly, Line 1 also supports overhead lines in certain stretches and depots. This allows Line 2 and 3 trains to use Line 1 tracks when traveling to a depot. Lines 4 and 5 use a third rail system, which also operates at 750 V DC. 


The metro is more than just a city service; it is a massive interconnected system. It serves 13 neighboring municipalities, including Assago, Rho, and Sesto San Giovanni. The metro also links directly to the suburban railway network through 14 different interchange stations. This connectivity allows people to travel from the heart of Milan to the wider Lombardy region. The system's scale is impressive, with Line 1 covering 26.7 kilometers and Line 2 covering 39.9 kilometers. Even the newer lines are significant, such as the 15-kilometer Line 4. As the city grows, the metro continues to expand through new extensions and planned projects.
