Whether you're a seasoned commuter or a first-time visitor venturing into the depths of the urban jungle, understanding the intricacies of the metro system is crucial for navigating the bustling city efficiently. This comprehensive guide will illuminate the ins and outs of the metro, empowering you to become a master of the subterranean domain.

History and Expansion

The metro, a lifeline for millions, has a rich history that spans centuries. The first underground railway system was established in London in 1863, revolutionizing transportation and setting the stage for the global expansion that followed.

Since its inception, the metro has undergone countless expansions and upgrades, with new lines and stations added to cater to the ever-growing urban population. Today, major cities worldwide boast extensive metro networks, connecting every corner with unparalleled convenience.

Types of Metro Systems

Metro systems vary in design and infrastructure depending on the city they serve. The two main types include:

- Heavy Rail: Typically characterized by large, deep-tunnel trains that travel long distances at high speeds. Heavy rail systems often serve as the backbone of urban transportation networks, connecting major centers and suburbs.

- Light Rail: Smaller and more agile than heavy rail, light rail trains run on elevated tracks or at street level. They offer increased flexibility and accessibility, particularly in densely populated urban areas.
