The first subway, which opened in London in 1863, has undergone significant transformations over the years in terms of technology, design, and service. Initially powered by steam locomotives, modern subways now utilize electric trains, enhancing efficiency and reducing pollution. Infrastructure improvements have included the expansion of networks, the integration of advanced signaling systems, and the introduction of automated services. Additionally, accessibility features and safety measures have been significantly upgraded to accommodate a diverse range of passengers.
