SINGAPORE, Dec. 28 -- The Johor-Singapore Rapid Transit System (RTS) Link reached a major milestone on December 26 when its first train successfully completed a dynamic test run on the mainline, signalling tangible progress on the long-delayed cross-border rail project.

In a Facebook post yesterday, RTS Operations (RTSO) said the test train departed from Singapore's Wadi Hana Depot, passed Bukit Chagar Station, travelled along elevated viaduct sections and reached the international border before returning safely to the depot.

The run marked the first of a series of dynamic tests under the project's testing and commissioning programme, which will intensify over the coming months as the system moves towards operational readiness.
