London's Tube network is on course to record its most reliable performance figures in a decade.
Despite the figures, Mayor of London Boris Johnson believes his team can provide an even better service and cut delays by a further 30 per cent.
A huge range of projects are underway, all designed to improve journeys for Tube passengers.
However, Mr Johnson also warned that if any of the planned work was to be cancelled, then Londoners would see these hard fought improvements slip backwards.
London Underground will invest a billion pounds in improving and upgrading the Tube over the next 12 months.
A range of new techniques are being brought in to predict when maintenance work is required on the lines to prevent unexpected equipment failure.
Mayor of London Boris Johnson, said: "Million's if Londoners and visitors to our great city use the Underground every day and we need to harness every single method we can to run the slickest possible operation on the Tube.
"I believe that by doing so we could cut Tube delays by 30 per cent by 2015. Without the long term investment we are making and the focus my team is providing on improving passengers journeys, there would be a real danger that the Tube would have taken one step forward then five steps backwards."
