Thank you for that, and obviously action has been taken since I last raised this issue. But also since I last raised this issue we've had a continuing spate of incidents, notwithstanding the reduction recorded by London Underground. We had a steel bolt thrown through a train window when it was travelling at speed, nearly injuring passengers. We've had the embankment set on fire alongside Goodmays Park, which actually stopped the whole system and potentially endangered the whole trainload of passengers. We have children still getting on to the lines.
Is there anything else you have planned to deal with this type of problem, particularly as you will take control and responsibility for the Underground in the near future?
