Subway schedules provide information on the times trains arrive and depart at various stations. They help passengers plan their journeys by showing the frequency of trains, especially during peak and off-peak hours. Schedules can vary by day of the week and may change during holidays or special events. Most subway systems offer printed schedules at stations and online access through their official websites or mobile apps. Riders can also find real-time updates on train arrivals, delays, and service changes, ensuring they have the latest information for their travels on the subway network.
