He said the ministry received feedback from the public requesting it to include and improve the Ampang line in the expansion plan, especially around Puchong and Serdang area.
"The ministry has just completed tackling the extension of the rail service from Kelana Jaya to Subang.
"We will be conducting the same process as we did when tackling the Kelana Jaya extension, including conducting public hearing and also town hall meetings, for the expansion of the rail service from Ampang to Puchong-Serdang," he said.
He was speaking to reporters after launching the "Hope and Train 2009/2010 Appreciation Ceremony" at Taylor's University College new campus here.
Ong said the ministry received an overwhelming support for the expansion of the Kelana Jaya-Subang rail last year and decided to conduct the same process for the Ampang line.
He also said that the public also wanted the LRT service to be improved including shortening the waiting time for coaches.
"As improving public transportation is one of priorities in the National Key Result Area (NKRA), it is the responsibilities of the ministry to improve the LRT system," he said.
The Ampang LRT line extension will begin from the Sri Petaling Station passing through Kinrara and Puchong before ending at Putra Heights, covering a distance of 17.7km with 13 new stations.
Asked whether the Ampang LRT line would also be using new coaches like the Kelana Jaya LRT line, Ong said the ministry was looking into it.
The extensions for the Kelana Jaya and Ampang LRT lines are estimated to cost RM7 billion and managed by Syarikat Prasarana Negara Berhad (SPNB).
