Today we are remembering those who lose their lives and were injured in the 7/7 bombings on the London transport network.
On 7 July 2005, bombs were detonated on three London Underground trains shortly before 9am and another on a London bus an hour later. 52 people lost their lives and over 700 people were injured.
In the aftermath of the incident it was the key workers, from transport and emergency services, who led the response and through their efforts were able to save lives and support the injured.
Mick Whelan, ASLEF general secretary, today paused to reflect on the events fifteen years ago.
He said: 'We must never forget those impacted by the loss and tragedy of 7/7 and be vigilant to ensure that it does not happen again. As we remember the victims and families we all give thanks to the staff and emergency services that not only gave succour but prevented much greater loss of life and hurt.'
