At least 19 people were killed Saturday when a passenger train slammed into another in Indonesia's Central Java province, police said.
"We're still collecting information but so far 19 people have been killed," said a police officer in Pemalang district, dpa reported.
The state Antara news agency, quoting an unnamed railway official, said 33 people died and 10 others were injured. It said more victims were still trapped in the wreckage.
The Argo Anggrek train was travelling from Jakarta to the Central Java capital, Semarang, when it ploughed into the stationary Senja Utama before dawn.
In a separate accident Saturday, one person was killed and four others injured when one train crashed into another in the Central Java city of Solo, Antara reported.
Bambang Ervan, a spokesman for the Transportation Ministry, said officials from the National Transportation Safety Commission were on their way to the scene to investigate the Pemalang accident.
"We want to know why the Senja Utama stopped," he said, adding that initial information put the death toll at nine.
Train accidents are not uncommon in Indonesia, which is still struggling with dilapidated transport systems.
