The Delhi Metro project was undertaken to provide a sustainable public transport system for Delhi's growing population. It was implemented in phases and faced challenges including land acquisition, underground construction, and signaling issues. Careful planning and leadership from Dr. E. Sreedharan helped overcome these challenges. Notable aspects included the decision to use standard gauge track, financing support from JICA, and an emphasis on safety, cleanliness, and stakeholder engagement. The metro has been successful in reducing traffic and pollution while symbolizing Delhi's modernization.
