Hong Kong's East Rail Line Services Disrupted by Signalling Faults

On April 25, 2024, Hong Kong's East Rail line experienced significant service disruptions lasting over five hours due to signalling system faults. The incident marked the seventh such disruption across the MTR network this year, highlighting a concerning trend that lawmakers anticipate will persist due to the slow progress in upgrading the decades-old signalling system.

The disruption occurred during both morning and evening peak hours, causing trains to run at reduced frequencies and leading to delays for commuters. According to the MTR Corporation, the issue stemmed from a failure to properly adjust a signalling component following replacement work.

While the East Rail line currently operates using the new signalling system, earlier disruptions this year have primarily affected other lines still relying on the outdated system. The MTR Corporation had initially planned a comprehensive signalling upgrade in the early 2010s. However, the project encountered a major setback in 2019 when a train collision occurred during testing, resulting in a suspension of the upgrade and a delayed implementation now expected by 2025-26.

Engineering teams from the MTR Corporation worked diligently to address the issue, successfully completing the replacement and calibration of a critical track component at Sheung Shui Station. The component, a track switch responsible for directing trains towards Lo Wu and Lok Ma Chau, was replaced during non-operational hours on April 24 but initially faced calibration issues that hindered smooth operations. As a result, the MTR Corporation had to adjust train schedules during peak hours on April 24 to accommodate the unexpected problem, which had the potential to cause significant delays on one of the city's busiest commuter lines.

Thanks to the dedicated efforts of the engineering staff, who worked tirelessly overnight, the component was fully operational by the early hours of April 25, enabling services to resume normal schedules in time for the morning rush.

Why this matters: The recurring signalling faults on Hong Kong's MTR network underscore the urgent need for a comprehensive upgrade of the aging infrastructure. As one of the world's busiest and most efficient public transportation systems, the MTR plays a vital role in the daily lives of millions of Hong Kong residents. Addressing these issues promptly and effectively is critical to maintain the city's reputation for reliable and efficient public transportation.

A lawmaker expressed concerns that the trend of signalling disruptions is likely to persist due to the slow progress in upgrading the outdated system. "The MTR Corporation had planned a signalling upgrade in the early 2010s, but the project encountered a setback in 2019 after a train collision during testing, leading to a suspension and delayed implementation now expected by 2025-26," the lawmaker stated. The MTR Corporation remains committed to resolving the issues and ensuring the smooth operation of the East Rail line and the entire MTR network for the benefit of Hong Kong's commuters.
