As of 2023, the actual incoming international railway passenger traffic in the UK stood at 10.64 million units. Forecasted data indicates a steady growth trajectory from 2024 to 2028. The year-on-year growth starts from approximately 0.93% in 2025, marginally increasing annually to reach a growth of around 0.9% by 2028.
