Rapid Bus began the first phase of the revamp of its bus network in January 2006 by introducing 15 City Shuttle bus routes which serve major areas in the central business district of Kuala Lumpur. The buses run between four hubs at the edge of the central business district, namely KL Sentral, Titiwangsa, KLCC and Maluri, and Medan Pasar in the city centre. These bus hubs also serve as rail interchanges, with the exception of Medan Pasar, although it is at a walking distance from Masjid Jamek LRT station.
