Quite a bit of headway has been made in the rail area since our last update in early February.
Our rail crews have hit the ground running in the new year, achieving a number of track laying-related milestones within the first month.
Most site operations over the Christmas and New Year period will stop on Thursday December 24 and recommence on Monday January 4.
With the end of the year in sight it's all hands on deck to finalise a number of jobs before the break.
While the majority of the new alignment is located underground, sections of track around High Wycombe Station and the adjacent stowage area, as well as at Bayswater Junction, are located at ground level.
