A train ticket is a document that allows a passenger to travel on a train. It typically includes information such as the departure and arrival stations, travel date, and seat number. Tickets can be purchased at train stations, online, or through mobile apps, making it convenient for travelers to secure their journeys. Train tickets can vary in price based on factors like distance, class of service, and time of booking. Some tickets are flexible, allowing changes or cancellations, while others are non-refundable. Passengers must present their tickets when boarding the train or during inspections by conductors.
