It’s another on-location #RailNatter! Join me and a motley crew as we explore one of Europe’s largest construction sites – High Speed 2’s Chalfont Lane staging point for the construction of not one, not two, not three but FOUR record-breaking things: the UK’s first and second longest railway tunnels, the UK’s longest railway viaduct, and Europe’s largest chalk habitat regeneration project.

This episode will look in detail at the HS2 Chiltern Tunnels, getting up close and personal with a tunnel boring machine and touring the factory that manufactures the tunnel lining segments. We’ll also go for a bit of a walk to explore the far reaches of the site…

Watch an excellent and decidedly more concise video from the day, with me popping up here and there, by @Geoff Marshall.
