The timeline for the submission of concept proposals for the Kuala Lumpur-Singapore high-speed rail project (KL-SG HSR) has been extended from November 15, 2023, to January 15, 2024. The extension was due to requests from more than 60 per cent of the international and local companies.

In July 2023, Malaysia-based MyHSR Corporation launched a request for information (RFI) to seek concept proposals for the 350-km-long HSR.
