It will be the third LRT line, and the fourth fully automated and driverless rail system in the Klang Valley region.

[9][10] Once completed, the line will form part of the Klang Valley Integrated Transit System.

The alignment is based on the Final Railway Scheme approved by the Land Public Transport Commission (SPAD).

The reasons cited for the changes made were due to the high cost of the project, unnecessary tunneling for the underground portion of the line and low ridership in the area.
