We dive into the intriguing topic of whether HS2 trains could cause a ‘sonic boom’ as they speed through the UK’s high-speed rail network. High-speed trains in other countries, like Germany and Spain, have experienced this phenomenon when entering tunnels, but what about the UK's HS2 project?

Join us as we explore the science behind sonic booms, the technology used to prevent them, and take a close look at the world-first Chilterns Tunnel south portal on HS2.

We also have an exclusive interview with Rail Minister Lord Hendy at the launch of Siemens Mobility’s new £100m research site in Chippenham.
