Putrajaya will study the feasibility of an alternative design for a portion of the Rapid Transit System (RTS) rail track provided by Johor ruler Sultan Ibrahim Sultan Iskandar.

Minister in the Prime Minister's Department Abdul Rahman Dahlan, who was granted an audience with the ruler last week, said Putrajaya took heed of the advice given.

"I had an audience with His Majesty last week, I went to see him and explained.

"Obviously, some of the perception that he had was based on third-party information, so we gave him the true story," Abdul Rahman reporters in Kuala Lumpur after the signing of the memorandum of understanding to form a joint venture company to build the Johor Bahru-Singapore RTS.
