The air-conditioned monorail zips from KL Sentral to Titiwangsa, linking many of the city’s sightseeing areas. There can be waits of up to 15 minutes between services and it gets packed during morning and early evening rush hours.
As well as buses, Rapid KL runs the Light Rail Transit system. There are three lines: the Ampang line from Ampang to Sentul Timur; the Sri Petaling line from Sentul Timur to Putra Heights; and the Kelana Jaya line from Gombak to Putra Heights. The network is integrated with the MRT and monorail lines but because all were constructed by different companies at different times, you may have to follow a series of walkways, stairs and elevators, or walk several blocks down the street to make connections.
Buy single-journey tokens or MyRapid cards from the cashier or electronic ticket machines. An electronic control system checks tickets/tokens as you enter and exit via turnstiles (you tap the token on the way in and insert it in the gate on the way out).
There are three main KTM Komuter lines: Tanjung Malim to Pelabuhan Klang, Batu Caves to Gemas and KL Sentral to Terminal Skypark (for Subang Airport). Trains run every 15 to 20 minutes during peak hours but there can be intervals of up to 45 minutes between trains at off-peak times.
Construction is ongoing for KL's MRT system. This rail-based public-transport network aims to ease the road-traffic congestion that plagues the Greater Kuala Lumpur/Klang Valley region.
The Sungai Buloh–Kajang line is operational, while construction is ongoing for the Sungai Buloh–Serdang–Putrajaya (SSP Line) – phase one of this line to Kampung Batu is scheduled to open by July 2021, with phase two to Putrajaya to be completed a year later.
