The rollout of the second and third lines, currently under feasibility studies of the Land Public Transport Commission (SPAD), is highly anticipated especially by the construction industry which was boosted by the multi-billion ringgit infrastructure, the most expensive the country has ever undertaken for the benefit of the people.

Other immediate economic advantages include creation of new jobs, townships and portfolio enhancement for those who are involved in the development of this massive project.

The estimated cost of the 51km SBK Line is MYR 23bn (USD 7.4bn) with 14,000-15,000 people involved.

Up to this point, the rolling out of the SBK Line has been without any major hiccups and delay, which MRT Corp CEO Datuk Azhar Abdul Hamid planned to replicate in the subsequent lines although the details were quite sketchy at this point of time.

Most likely, the feasibility studies of the subsequent lines will be completed in the second half of the year and the announcement will be made before year-end.

"Although it is still premature to comment on the subsequent lines, I would guess that line two or the circle line of the MRT should be shorter than SBK Line where the total length should not exceed 35 km.

"The circle line is important as it is going to connect with all the other lines such as the light rail transit and KTM Komuter," he said in Kuala Lumpur on 3 February 2013.

The Greater KL/Klang Valley Land Public Transport Master Plan draft has indicated that orbital movements in Kuala Lumpur would be addressed by the provision of a circle line that would link existing areas such as Mid Valley, Mont’Kiara, Sentul Timur and Ampang as well as proposed developments such as Matrade.
