The Malaysian government has sought proposals from private firms to develop Kuala Lumpur - Singapore high-speed railway(HSR).

The plan to construct a 350 km rail line connecting Malaysia and Singapore has been cancelled due to the inability to agree on proposed project changes. MyHSR Corp, the responsible organization, faced challenges in finding common ground. The project's estimated cost was approximately US$17 billion, attracting interest from companies in China, Japan, South Korea, and Europe for contracts related to the construction, operation, and financing of the trains and rail assets.

The project encompasses designing, constructing, financing, and maintaining all rolling stock and rail assets, including trackwork, power, signalling, and telecommunications. The HSR line will have 8 stations, with terminals in Bandar, Malaysia, and Singapore. There will be 6 intermediate stations in Putrajaya, Seremban, Ayer Keroh, Muar, Batu Pahat, and Iskandar Puteri. The trains will operate at speeds exceeding 350km/h. The HSR project aimed to enhance connectivity and facilitate faster travel, reducing travel time between the 2 cities to approximately 90 minutes. The HSR project was expected to have significant economic benefits, promoting tourism, trade, and business opportunities.
