How long does a train need to be late upon arrival at a terminal for it to be counted as late statistically?

For a train to be statistically counted as late upon arrival at a terminal, it is established that a delay of more than five minutes qualifies. This threshold is important for operational analysis and reporting purposes, as it enables transit authorities to assess performance, identify issues in scheduling, and improve service reliability. The five-minute mark acts as a standard across many transit systems, highlighting the significance of punctuality in maintaining operational efficiency and customer satisfaction. By using this measure, transit agencies can effectively monitor delays and implement strategies for improvement.
