JAKARTA (AFP) - Indonesia is investigating a series of malfunctions that have plagued its first light rapid transit (LRT) system just days ahead of the opening ceremony of the Asian Games, the transport ministry said on Monday (Aug 13).

The LRT in the city Palembang - which is co-hosting the Games with Jakarta - needs to be operating smoothly, as thousands of athletes, officials and visitors arrive this week for the start of the world's biggest multi-sport event behind the Olympics.

Indonesia has set aside worries about terrorism, street crime, venue completion and Jakarta's notorious traffic, saying it is ready to roll for the Aug 18 to Sept 2 Games.

But officials on Monday were forced to acknowledge a series of "shortcomings" with the LRT, seen as key to avoiding traffic snarls in Palembang on Sumatra island.

A short circuit knocked out power to a portion of the transit system on Sunday, halting trains and forcing passengers to disembark between two stations.

Just days earlier, passengers had to endure long delays due to signals interference, which caused the temporary suspension of services, local media reported.

"The government will immediately evaluate the whole operation of the South Sumatra LRT," said Mr Zulfikri, director general of railways at the transportation ministry, who like many Indonesians has only one name.

"(We) hope this evaluation will provide a solution that will improve the overall operation of the LRT," he added.

Jakarta and Palembang will host about 11,000 athletes and 5,000 officials from 45 Asian countries for the Games.

Indonesia has had less time to prepare than most host countries after it agreed to host the games only four years ago when Vietnam pulled out.
