A flash mob is a large group of people who get
together in a public place, perform an activity such as dancing,
and then disperse.
The events are usually organised on the
internet using applications such as Facebook and Twitter.
While the events are fun and generally
harmless, organising and participating in a flash mob at a railway
station can be unsafe. By their very nature, a flash mob brings a
lot of people into one place at the same time which can cause
overcrowding and disruption to passengers and staff at that
station.
We encourage anyone who intends to organise a
flash mob at a station not to, as past events have caused station
closures due to overcrowding, which affects those who are using the
network to travel.
We are not out to spoil the fun but we do need
to ensure the rail and Tube networks can continue to operate
without disruption. British Transport Police may turn you away
if we think you are entering a station in order to take part in a
flash mob. If you persist, you may commit an offence and face
arrest.
