Derailed trains, screaming passengers and a collapsed building – all elaborate props in Europe’s largest emergency simulation exercise held in Kent on Monday.
The staged scenario was carried out to prepare Britain’s emergency services for a potential large-scale operation.
The £800,000, four-day Exercise Unified Response was coordinated by the London Fire Brigade and funded by the European Union.
Some 4,000 people took part in the exercise, including 1,000 actors who played injured or killed rail users.
Although the exercise was made up to look like Waterloo Station in London, the staged catastrophe actually took place near Dartford.
