#DidYouKnow#Mumbai’s local rail network is the busiest commuter train system in the world; with 7.5 million people using the trains to commute daily, it is no surprise that overcrowding, here, reaches epic proportions. However, this is no mean feat, considering that the railways manage to ferry more people each day than you will find in an entire country like Switzerland or Bhutan. Annually, the local railways transport 2.2 billion passengers, which is about a third of the world’s population.
