By train
The easiest way to get to the City Centre is by rail, whether by light rail transit or the KTM Komuter. The monorail does not serve the City Centre.
The main stations of the Kelana Jaya LRT line are Pasar Seni and Masjid Jamek while the stations of the Ampang LRT Line in this district are Plaza Rakyat and Masjid Jamek. Take the Kelana Jaya Line to the City Centre if you are coming from the KL Sentral transportation hub in Brickfields.
If you are coming from the suburbs of KL, catch the KTM Komuter. The main stations in the district are Kuala Lumpur often referred to as the Old KL Station as opposed to KL Sentral, and Bank Negara, although there will be a fair bit of walking from both stations to get to any attraction.
Trains are very convenient for transportation in KL.
By bus
Almost all bus routes start and end in the City Centre. The main bus terminals are Pasaraman Kota or the Klang Bus Station, Terminal Sultan Mohamed or Pasar Seni opposite Pasarama Kota, Kotaraya Jalan Tun Tan Cheng Lock, Bangkok Bank Jalan Tun H.S. Lee, Sinar Kota Jalan Tun Tan Siew Sin, formerly Jalan Silang and Puduraya.
Some routes, especially those by RapidKL, may end at the outskirts of the City, such as at KL Sentral or Titiwangsa. You'll be able to catch connecting City Shuttles from this terminal into the City Centre. See Kuala Lumpur's Get Around section for route details.
Two new FREE bus services started 1st September 2012. The purple bus service starts at Pasar Seni and travels to the shopping area of Bukit Bintang where it links up with the green bus service that loops around KLCC. (http://www.spad.gov.my/ne...)
