As London bound trains depart the Colne Valley viaduct, a 880m tunnel awaits. After an embankment then overbridge over Breakspear Road South, followed by another overbridge over the river Penn. The line will then approach the London north tunnel portal at West Ruislip taking trains to Old Oak Common station.
2 ventilation shafts constructed above the tunnel. There will be 5 shafts in total. The eastern end of the tunnel is still under construction, base slab looks complete(?). Due to be finished early 2025
HS2 is the UK's newest high speed railway linking London to Birmingham and the north. Trains are due to cross the colne valley area here in the early 2030's.
A little off the beaten track for me but hope you enjoy the video of HS2's progress in 2024!
