The Mumbai Suburban Railway (Marathi: मुंबई उपनगरीय रेल्वे) (colloquially called local trains or simply locals)[2] consists of exclusive inner suburban railway lines augmented by commuter rail on main lines serving outlying suburbs to serve the Mumbai Metropolitan Region. Spread over 390 kilometres (240 mi),[3] the suburban railway operates 2,342 train services and carries more than 7.5 million commuters daily. The daily commuters constitute around 40% of the daily commuters of Indian Railways.[4][1] By annual ridership (2.64 billion), the Mumbai Suburban Railway is one of the busiest commuter rail systems in the world and arguably the worst rated by riders anywhere in the world.[5][6][7][8] It has killed estimated 50,000+ passengers in the last two decades without any significant upgrade in safety rules, infrastructure or future lookout.[9][10][11][12] Trains run from 04:00 until 01:00, and some trains also run up to 02:30 or 03:00. It is the first suburban rail network in India.
