BANDUNG: Four people were killed and at least 22 injured when two trains carrying hundreds of passengers collided in Indonesia on Friday (Jan 5), officials said.

The front carriages of both trains were a mangled wreck while others further back had derailed and overturned on a stretch of tracks cutting through rice fields in West Java province.

No fatalities have been reported among the nearly 500 passengers on board, with all four deaths reported so far involving train crew.

The crash between an intra-city train carrying 287 passengers and a local line with 191 on board took place at 6.03am local time near Cicalengka, railway operator PT KAI said.

"KAI is deeply saddened and expresses its condolences for the death of four train officers, who were train driver, assistant, steward and security guard," said a spokesman for the company.

The number of injuries reported have varied. Police have put the number at 37 while the railway operator said 22 people were injured.

Police spokesperson Ibrahim Tompo said all passengers have been evacuated with those injured taken to local hospitals.

But he said that a joint rescue team was still working to recover the body of one train crew member killed in the crash.

"One victim who is believed to have died still cannot be evacuated because the victim was buried in the material of the carriage," Tompo said.

CAUSE UNKNOWN

The cause of the accident is not yet known.

The Transportation Ministry has deployed teams to assist with the evacuation and conduct an investigation into the accident.

"We also apologise for this accident which has disrupted railway services, especially in West Java," said ministry spokesperson Adita Irawati.

Transport accidents are not uncommon in Indonesia, a vast archipelago nation where buses, trains and even planes are often old and badly maintained.

Last November, a collision between a train and a minibus at a level crossing in Lumajang, East Java province, killed at least 11 people and injured several others, an official told local media.

In 2015, 16 people were killed after a commuter train crashed into a minibus on a level crossing in the capital Jakarta.

In 2013, seven people were killed and scores more injured when a commuter train collided with a fuel tanker in Jakarta and burst into flames.
