Page "London Underground" Paragraph 22

Accidents on the Underground network, which carries around a billion passengers a year, are rare.

There is one fatal accident for every 300 million journeys.

There are several safety warnings given to passengers, such as the ' mind the gap ' announcement and the frequent announcements to passengers to keep behind the yellow line.

Relatively few accidents are caused by overcrowding on the platforms: staff monitor platforms and passageways at busy times and prevent people entering overcrowded areas.
