The MRT Line 2 has a total length of 57.7 kilometers, with 38.7 kilometers of elevated sections and 13.5 kilometers of underground sections, and 36 stations (9 underground stations and 27 elevated stations). The project was divided into two phases. The phase 1, which runs from Kwasa Damansara to Kampung Batu for 18 kilometers, had already started operation on June 16, 2022. The Phase 2, from Kampung Batu station to Putrajaya Sentral station, is 39.7 kilometers long. The Phase 2 started operation on March 16, 2023.

The MRT Line 2 serves as the "artery" for the Greater Kuala Lumpur's rail transit network, running from north to south. Once operational, it will enable more than 2 million residents along the line to enjoy a "half-hour living circle" with a daily ridership of over 100,000 people, significantly alleviating local traffic congestion and residents' travel problems.
