The Electrified Double Tracking Project consists of two phases: Phase 1 between Subang Jaya and Subang Skypark, which was awarded to Konsortium Skypark Link-Lion Pacific Sdn Bhd, and phase 2 from Subang Skypark, through Kampung Melayu Subang and Ladang Elmina and ending at KTM/MRT Sg.
Buloh to allow rail cargo traffic to bypass downtown Kuala Lumpur.
However, unconfirmed reports state that alternative plans, including an extension of the ECRL to Serendah instead of extending the Skypark Link, were being studied.

The construction of the link was funded by the Ministry of Transport to provide rail-based public transport to connect the Sultan Abdul Aziz Shah (SAAS) Airport Terminal 3 (Terminal Skypark) and its vicinity with the existing KTM railway.
The RM521 million rail link was commissioned in 2013 with an initial completion date in 2016, but this was later extended to 2018.

The project consists of two main parts: an at-grade section between Subang Jaya and the old Sri Subang spur line for the length of 4.09 km using the existing railway reserve previously funded by Petronas to transport fuel from Port Klang to the airport, and a new section between the new location of Sri Subang for the total length of 4.067 km which is elevated rail track along the existing Sungai Damansara river reserve, ending at the car park just outside Subang Skypark.
