There could be a few factors:  

• Alerts are only sent if a train is predicted to be delayed by 10 minutes or more. Predictions update as the system tracks the train via GPS and rail monitors. 
• Delay estimates are based on GPS data, the train’s position, and an algorithm that considers other trains. External factors like temperature, station issues, and track incidents can also affect accuracy. 
• Train cancellations may be announced after the scheduled departure or mid-service. Alerts are sent immediately once a cancellation is confirmed. 
• New factors, such as police or fire activity, can also affect train status decisions and the timeline to receive an alert.
