A deadly train fire aboard a sleeper-train in India has left at least 47 passengers dead.

FOX News Radio's Alastair Wanklyn reports:

The fire broke out when passengers were asleep aboard an overnight train from New Delhi to Chennai.

One who escaped says one set of carriage doors would not open, and many people were trapped. As the train passed a station officials got the driver to stop. They say the fire began after an electrical fault.

( Man)"Everybody sympathizes with the affected families."

India's railways have a grim casualty toll, figures show in the past five years, more than 1,200 people have died, mostly in accidents.
