The Kuala Lumpur monorail system in Malaysia opened 31 August 2003, and serves 11 stations running 8.6 km with two parallel elevated tracks. It connects Kuala Lumpur's main station KL Sentral with the "Golden Triangle". It was built for RM1.18 billion by KL Infrastructure Group Berhad (KL Infra) that holds a 40-year concession to operate the monorail. The system utilises permanently coupled 2-car trains, which are able to accommodate 158 passengers each during regular operations. The monorail carriages themselves were built by a Malaysian company.
