What does peak and off peak mean for trains?

Peak and off-peak refer to the times of day when train services experience the highest and lowest passenger demand, respectively. Peak times typically occur during morning and evening rush hours when commuters travel to and from work, leading to higher ticket prices and crowded trains. Off-peak times are generally during mid-morning, early afternoon, and late evening, offering lower fares and less crowded conditions. Understanding these terms helps passengers plan their travel more efficiently and economically.
