Paddington Rail Crash: James Nesbitt explores some of Britain's most tragic disasters, starting with the 1999 rail accident at Ladbroke Grove in London. This series unpicks the events that led to the most devastating disasters of the past 60 years. The unique documentary shines a spotlight on the human cost of the tragedies while seeking to explain the wider political, cultural and institutional context that contributed to them – and looks at the changes made in the wake of each disaster. With individual narratives explored by journalists, the series asks why warning signs were often ignored and how seemingly innocuous decisions – sometimes decades before – contributed to the events that changed post-war Britain forever.
