In today’s fast-paced urban life, metro systems are important for easing traffic and keeping cities moving. Among them, the Shanghai Metro in China stands out as both the busiest and the longest in the world. Spanning vast distances and connecting hundreds of stations, it is a remarkable example of modern engineering and urban planning, offering millions a quick, reliable, and affordable way to travel each day.

The Shanghai Metro began operating in 1993. It just had a few lines back then, but it has expanded tremendously over time.  Its current network spans over 831 kilometers, which is more than the distance between Delhi and Mumbai.  Almost every part of the city is covered by its 20 lines and 508 stops.

Millions of people use the Shanghai Metro every day to travel to markets, work, school, and other locations. The trains are renowned for being quick, hygienic, and well-run, and they operate both overground and underground. Thanks to technology and careful planning, the system functions flawlessly even during peak hours.

Even more amazing is how the subway has contributed to Shanghai's development. More people can now live further away from their places of employment and yet get there on time because to the metro's ability to connect distant areas to the main metropolis.  Additionally, this has reduced pollution and traffic on the roads.
