The Ringgits 55bn project involves building a 538.5km electrified main line linking the capital Kuala Lumpur and the Klang Valley conurbation with the less-developed regions of Pahang, Terengganu and Kelantan, together with 66.5km of branch lines and connections to the existing network.

A groundbreaking ceremony was held in August 2017 and the project is due to be completed in 2024.
