Tsunami 2004: Sri Lankan train guard's story

When the 2004 Indian Ocean tsunami hit Sri Lanka, it derailed a train that was taking passengers from the capital Colombo to Sri Lanka's southern city Galle.

The force of the wave took away at least 802 lives and hundreds of people remain unaccounted for.

It is believed to be one the worst train disasters in the world.

Ten years on, the BBC met with the train's guard Karunathilake, who still works the same route.
