The Johor Bahru–Singapore Rapid Transit System is an international cross-border rapid transit system that will connect Johor Bahru, Malaysia and Woodlands, Singapore, crossing the Strait of Johor.
It will consist of two stations, with the Malaysian terminus at Bukit Chagar station and the Singaporean terminus at Woodlands North station, which also interchanges with Singapore's Thomson–East Coast MRT line.
Both stations will consist of co-located customs, immigration and quarantine facilities of both countries. When built, the RTS Link will be the second rail link between the two countries after the KTM Intercity's Shuttle Tebrau, between JB Sentral and Woodlands Train Checkpoint. However, the RTS Link is expected to replace this shuttle once it is completed.
A joint operating company between Singapore's SMRT Corporation and Malaysia's Prasarana will be the operator of the link. Construction started on the Malaysian section on 22 November 2020 and on the Singaporean section on 22 January 2021.
