Tom Holland and Iszi Lawrence follow history’s lines and linkages to uncover connections and compelling stories.

As the new HS2 rail link between London and Birmingham begins its first construction phase, Tom joins the railway archaeologists who’ve been excavating one of London’s ancient graveyards along the new line.

And, further down the communications corridor, the programme explores the history of protest in the face of transport progress.

Also, with centuries-old woodlands being displaced by new roads and railways, we look at Britain’s ancient sylvan history.
