New Delhi, India (CNN) -- Twenty people were killed and 30 injured Monday when a freight train collided head-on with a passenger train waiting at a station in central India, officials said.
The crash took place in the state of Madhya Pradesh, said railway spokesman Anil Saxena. Ten of the injured were seriously hurt, he said.
Authorities could not immediately say what caused the crash.
India's massive rail network, used by hundreds of thousands of passengers daily, has a poor safety record.
Official figures show 100 train accidents occurred in the country in the 2009-10 fiscal year and 115 in 2008-09.
