Synthesis/Conclusion:

The Sengkang-Punggol LRT network experienced a significant service disruption due to a power trip caused by a cable fault. The incident highlights the challenges of maintaining aging infrastructure and the potential impact of external factors like lightning strikes. While SBS Transit is undertaking upgrades, regular inspections and thorough assessments of the impact of faults on surrounding infrastructure are crucial to prevent future disruptions and ensure reliable service for commuters.
