In early September 1940, crowds gathered outside Liverpool Street underground station demanding to be let in to take shelter from the first bombings of what would become known as 'The Blitz'.
A 1924 Government directive had ruled out the use of stations as shelters in the event of air raids but Londoners had other ideas. Many bought tickets for the tube and then simply refused to leave. This prompted the London Passenger Transport Board (LPTB) to take control.

Once the decision was made to formally admit shelterers, they came in their thousands. On the 21st September 1940 around 120,000 people were seeking refuge in London's underground stations. By October this had risen to 124,000, with 2,750 sheltering just at King's Cross
Safety below ground was a major concern for the LPTB and shelterers were constantly requested to comply with 'conditions of use'.
Rules included: have your shelter ticket ready to show on entry; arrive after 18:30; leave by 07:00; don't stand in groups; keep away from the platform edge; control children; take your rubbish home; and cooperate with staff

"they didn't want the kids walking about because the trains were running...they'd start playing about on the escalators...there was one kid, one night, got his fingers caught in the belt..."
Another concern was the shelterers well-being. One unpleasant experience of sheltering underground was the presence of mosquitoes.

Particular attention given to the elimination of mosquitoes
By February 1941, "good progress" was being made on the delivery of sprays and compressors for aerial disinfection. One report noted that "spraying may be discontinued while the shelterers are sleeping but should recommence during the coughing period in the morning"
'Elsan' potable toilets were provided at shelters as well as more rudimentary buckets. But the ratio was never good - at Holborn there were just 4 elsans and 4 buckets for a station that could hold 4600 people.
24,000 bunks were installed at various stations, particularly in newly built deep level shelters and sidings. If placed end to end they would have stretched for 27 miles.
Cigarette machines were installed at stations such as Clapham South, South Wimbledon, and Colliers Wood.
Where possible, entertainments were provided or encouraged for shelterers.

Generally, those sheltering tried to maintain their spirits - if only for the sake of the estimated 25,000 children who were in the stations nightly at the peak of the war.
Some stations held children's parties, part of Gloucester Road station was converted into a playground!

Even Christmas remained as a celebration.
But a war was still raging above and tragically some stations took hits from bombs, both indirect and direct.

The following night 19 people lost their lives as Bounds Green station was hit.

On 14th October, Balham station was flooded after a bomb fell above, 64 died. At Bank station on 11 January 1941, 53 people were killed when a bomb hit the booking hall.
Sadly, not all deaths were as a result of bombing - on 3rd March 1943, 173 people seeking shelter lost their lives at Bethnal Green after a woman tripping led to mass crushing. Other accidents included an individual falling against a train. Minor injuries were also a risk.
But in the midst of chaos and tragedy there was also life.
