DISCUSSIONS are under way on the proposed rapid transit system (RTS) linking Singapore and Johor, Foreign Minister George Yeo told the House yesterday.

The areas being explored include whether the RTS should be above or under water, and how to link it to the public transport networks in both countries.

'The RTS link will be a major infrastructural project,' Mr Yeo said. 'Both sides are doing detailed studies and they have to meet to discuss what will best serve their mutual needs in the most cost-effective way.'

Engineering studies and cost analyses have to be undertaken, he added.

The RTS, which should be up and running by 2018, was agreed to in May as part of the breakthrough negotiations over Malayan Railway land.

Mr Yeo was responding to a question from Madam Halimah Yacob (Jurong GRC), who had asked for an update on the Malayan Railway land swop, which got the green light last month.
