On Tuesday, multiple train services across various regions faced significant disruptions. In Bengaluru, a power supply fault disrupted Metro services on the Green Line for over an hour, causing peak-hour chaos. In Kerala, waterlogging led to the full or partial cancellation of several trains, with the Railways deploying a special train to mitigate the inconvenience. A signalling glitch at Chhatrapati Shivaji Maharaj Terminus in Mumbai delayed Central Railway's suburban services by 45 minutes. In the UK, trains between Southampton Central and Salisbury were cancelled due to a signalling fault, with disruptions expected until 11:00 BST.
