I am happy to go with my hon. Friend, at his convenience, to Greenford station. He would have found the escalator working this morning. London Underground's investment programme is a substantial one. It includes, for example, complete refurbishment and modernisation of the Angel station at a cost of £70 million, and the introduction of a new service on the Central line at a cost of £700 million. That is evidence of London Underground's massive investment programme, which includes the modernisation or replacement of escalators.
