RapidKL Rectified Signalling Issue by Operating Trains in Manual Mode

RapidKL addressed the intermittent signalling communication problem between Batu 11 and Kajang by implementing manual mode operations for trains. This measure allowed services to resume and was expected to return to normal within approximately 30 minutes of the rectification. The issue, which began at 4:29 PM, caused significant delays during the evening rush hour.
Signalling Communication Interruption

The disruption to the Sungai Buloh-Kajang MRT line service was officially attributed to intermittent signalling communication that was not responding properly. This technical fault occurred at 4:29 PM, impacting the segment between Batu 11 and Kajang. The inadequate response of the signalling system directly led to the train service delay, affecting commuters during a peak travel period.
Manual Mode Operation as a Solution

Following the identification of the signalling issue, RapidKL implemented a workaround by directing trains to operate in manual mode. This operational adjustment allowed trains to continue moving along the affected stretch of the line, albeit under direct control rather than the automated signalling system. This step was crucial in restoring some level of service continuity while a more permanent fix was underway.
Service Normalisation Timeline

RapidKL indicated that the train services would regain momentum and return to their normal operational status within half an hour of the signalling issue being rectified. By 5:14 PM, approximately 45 minutes after the initial announcement, the company stated that the signalling problem between Batu 11 and Kajang had been resolved. This projected timeline aimed to manage commuter expectations regarding the restoration of full service.
Commuter Dissatisfaction with Announcements

Despite the operational measures taken by RapidKL, many commuters expressed frustration on social media regarding the delay and the clarity of announcements. Several passengers reported being stranded at stations for extended periods, with a lack of clear instructions on whether to alight or remain on the trains. This communication breakdown contributed to a negative experience for those affected by the service disruption.
