In what way can adverse weather complicate train schedules?

Adverse weather can significantly disrupt train timetables due to various factors associated with operating in less-than-ideal conditions. For instance, severe rain, snow, or high winds can reduce visibility and track conditions, which may necessitate slower speeds or increased caution, ultimately leading to delays. Additionally, weather-related events such as flooding or ice can obstruct tracks or create unsafe conditions, requiring trains to be rerouted, temporarily suspended, or operated on altered schedules. As a result, the overall reliability and timing of services may be adversely affected, causing a cascading effect on the entire rail network's on-time performance.
