The 2006 West Bengal train disaster was a fatal suspected terrorist explosion on a train travelling between New Jalpaiguri and Haldibari that occurred on November 20, 2006, when the train was in a remote part of West Bengal State, India. Five people were killed, and between fifty and twenty-five were injured, although home secretary Prasad Ranjan Ray says officials believe there may in fact be as many as sixty-six injured. Two passenger cars were damaged. The explosion was due to a still-undetermined cause, but terrorism is suspected. The train was about from Kolkata.
