NETWORK Rail has announced engineering projects will disrupt West Coast Main Line operations over four Bank Holiday weekends in spring/ summer 2021.
Two lines into Euston station will be taken out of service for two six-week periods - April 2-May 17 and July 17-August 31 - to enable the new HS2 terminus to be built.
Weekend work will also take place between April and the end of August.
Most train services will continue running, but there will be some timetable and platform alterations.
Network Rail has detailed other planned work on the WCML for major track renewals between Rugby and Birmingham, Crewe to Warrington, Preston to Lancaster and Carstairs to Carlisle.
