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 18 August -2 September 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 Sunday, halting trains and forcing passengers to disembark between two stations.
