A train delay occurs when a train does not arrive or depart at the scheduled time. Delays can happen for various reasons, including mechanical issues, weather conditions, or unexpected events on the tracks. Passengers may experience inconvenience and may need to adjust their travel plans accordingly. Train delays are often communicated through announcements at stations or via mobile apps. Many train services provide real-time updates to keep passengers informed. Understanding the cause of a delay can help travelers manage their time better and make alternative arrangements if necessary.
