Services were suspended for hours, with passengers facing long queues and uncertainty. While repairs were underway and some services began to resume on Wednesday, significant delays and cancellations persisted, prompting operators to advise passengers to postpone journeys. The incident affected one of Europe's busiest rail corridors during peak holiday travel.
