While The Front Page is taking its summer break, we will be shining a spotlight on some of the biggest podcasts and news events from the New Zealand Herald network over the last year.

This year marks 70 years since the Tangiwai rail disaster. 151 people died after the Wellington to Auckland express derailed, due to a lahar washing out the rail bridge over the Whangaehu river.

The tragedy is remembered as our worst ever rail disaster, but did we learn any lessons from this incident? In this collaboration between the NZ Herald and the Motuihe Group, broadcaster Hamish Williams seeks to answer these questions.

Listen to this excerpt from the first episode, and for the full season of Tangiwai – A Forgotten History, find it on iHeartRadio or wherever you get your podcasts.
