What we are doing
Update: We planned to carry out these works from 29 May to 19 June 2025. The dates has now changed.
These works have started but will now continue until 7 July 2025.
We will be building cross passage 17 near Station Approach, Greenford. Cross passages will be built between the railway tunnels to allow HS2 passengers to get to a place of safety in an emergency. They will be located approximately 500 metres apart along the tunnels route.
To build the cross passage, we will need to break into the side of the completed tunnel. This might generate some noise and vibration which may be heard or felt as groundborne noise in nearby buildings. We’ll work 24 hours, seven days a week. To avoid overnight disturbance, we’ll limit noisy activities to between 7am and 10pm Monday to Friday, 7am to 6pm on Saturday and 10 am to 3pm on Sunday and carry out quieter works at night.
Cross passage 17 is about 29 metres below ground and 50 metres away from the closest property.
