#RailNatter Episode 153: High Speed 2 - taking a look inside a tunnel boring machine

Precisely one year ago, a few folks and I had the delight of a tour inside one of HS2's tunnel boring machines as it scoured its way underneath Long Itchington Wood in Warwickshire... And what a spectacular experience it was!

Hopefully I'll capture some of that excitement and energy as I bring you along on the tour with me... And will I unlock the mystery of the pink helmet?
