Ten tube stations on the Jubilee, Piccadilly and Northern lines have been refurbished as part of Transport for Londons five-year 10 billion upgrading scheme for the London Underground. The stations now have new tiling and paintwork, new lighting, clocks and seating. PA systems have been modernized and extra help points installed, while the number of CCTV cameras over the ten stations has risen from 201 to 710. The stations historic features have either been restored or replaced with exact replicas. The upgraded stations are St Johns Wood, Stockwell, Golders Green, Morden, Manor House, Turnpike Lane, Ealing Common, Caledonian Road, Boston Manor and Sudbury Hill.
