Indonesia ? A train crash in central Indonesia killed at least 36 people and injured dozens Saturday, many of them critically, officials and witnesses said.

The toll was expected to rise with some bodies still trapped in the mangled wreckage.

The accident occurred at a station in Petarukan, a city on the northern coast of Central Java province, at around 3 a.m. (8 p.m. CDT Friday) as many passengers were sleeping, witnesses told TVOne.

A train from the capital, Jakarta, slammed into a train sitting idle near the platform, causing severe damage to both.
