The Parliamentary Under-Secretary of State for Transport (Lilian Greenwood)

The Department recognises the critical importance of the east coast main line and has invested £4 billion in a combination of infrastructure enhancements and rolling stock upgrades that will help to deliver journey time, reliability and capacity improvements. The full benefit of this investment will be felt with the introduction of a revised timetable in December 2025. The Department continues to work closely with Network Rail to explore opportunities to improve performance and resilience.
