HS2 Amersham Tunnel & Ventilation Shaft | UK High-Speed Rail Construction Update 2025

Explore the hidden world of HS2 in Amersham!
This video takes you inside the HS2 Amersham Tunnel and its newly built ventilation shaft near Amersham Hospital. Part of the Chiltern Tunnel, this section is a vital part of the UK’s high-speed rail project (HS2 Phase One), connecting London to Birmingham.

With over 40 miles of tunnels now excavated, the HS2 Amersham tunnel shows the scale of engineering and construction happening across the UK. We’ll explain how the ventilation shafts regulate air, keep trains safe at high speed, and provide emergency access for fire and rescue teams.

Whether you’re following HS2 construction updates, passionate about tunnelling, railways, engineering, or UK infrastructure, this video gives you a clear look at progress in Buckinghamshire. Subscribe for more HS2 news, train design updates, and UK railway documentaries.

Dear Loyal Patrons
We are slowly growing this channel and growing it together to 1000 subscribers and beyond! I filmed this on a morning when I had a late shift on. I bumped into an older gentleman who was amazed by what drones could do as he gazed at my hand held controller monitor. I gave him my business card and said to follow my channel on YouTube. With your help, please share this video to anyone who would find these development of interest to them. Please leave your thoughts in the comment section! I enjoy reading the debates that spring up.

Best regards,
James
