When the port was claimed by the Portuguese Empire, they saw it as a natural water bay and as such, named it ‘Bom Bhaia’ which translates as ‘good bay’. In 1661, King Charles II of England married the Portuguese princess Catherine of Braganza and as part of her dowry, Charles received the ports of Tangier and the Seven Islands of Bombay (which he leased to the British East India Company). For over 300 years the city was known as Bombay, until 1995 when the ruling regional political party Shiv Sena changed the name to Mumbai.

The enormous complex network is so well maintained with a near-perfect success rate, that Forbes magazine has awarded the network with its highest rating, Sigma Six – a rating shared with corporate giants like General Electric and Motorola, which signifies less than one error per one million transactions.

#16: World’s Busiest Rail System


india train

A network spanning over 465 kilometres, Mumbai’s trains carry almost 7 million passengers a day. The city’s railways also have one of the highest passenger densities in the world.

During rush hours (that’s hours, not hour), each train carriage is rammed with around 500 people, yet they were only designed to carry 188 people. Thats roughly 14-16 people per square metre – double the recommended figure. The rail staff have coined a term for this phenomenon: Super-Dense Crush Load.



#17: There is Just 1.1 Square Metres of Open Space for Residents of Mumbai


The metropolis is so densely populated that finding an empty space (or even privacy) is nearly impossible. Mumbai is one of the busiest, gridlocked, and highly populated cities on earth, and is the most cramped city on the planet – there is less space per person than in New York, Mexico City, Shanghai, Hong Kong, and yes, even Tokyo!



#18: A Deadly Rail System


Around 3,500 people die from train-related accidents each year in Mumbai alone – thats the equivalent of about 10 people per day! There are a number of factors – mainly, passengers falling or being pushed off carriages travelling too fast, or overcrowded, and people fatally injured whilst crossing railway tracks. There are pedestrian overpasses at every station, but many passengers chose to save a few minutes by crossing the tracks instead!

While statistics like this would be enough to shut down entire rail networks in other countries, Mumbaikars roll on, incredibly enough.



#19: Mumbai also has the Most Obsolete Electric Rail Line in India


Installed way back in 1925, this means that instead of there being a third rail on the ground powering the trains, the cables are overhead. This is also one of causes of deaths among passengers that sit atop overcrowded carriages.
