These photos of India's overcrowded railways will make you grateful for your commute

India has the second largest rail network in the world. That, combined with the fact that 23 million passengers a day ride its rails, help to explain why its trains are so overcrowded that you can often see passengers hanging out the side.

It's a long-standing tradition to take the train in India - the oldest train in the world, built in 1855, also runs on the India rail network between New Delhi and Rajasthan.

If you think your commute is bad, or airport lines are giving you the travel blues, just take a look at these insanely crowded trains in India.

You might feel a little less claustrophobic.
