GTR is working with Network Rail and local partners to explore potential timetable, rolling stock and infrastructure improvements to increase capacity through Harpenden. That follows long-term demand forecasting, which indicates continued passenger growth driven by planned housing development and the expansion of Luton airport, which the hon. Lady references. I will be glad to continue working with her to ensure we get the capacity improvements that we need over time to meet the needs of her constituents.
