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.

india train

A network spanning over 465 kilometers, 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 meter – double the recommended figure. The rail staff has coined a term for this phenomenon: Super-Dense Crush Load.

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

The metropolis is so densely populated that finding an empty space (or even privacy) is nearly impossible.

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 pedestrian overpasses at every station, but many passengers chose to save a few minutes by crossing the tracks instead!

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.
