Until Tube Lines and LUL agreed the principles about data to be submitted to the MPD in early 2004, limited capital projects information was passed to LUL. Since then, Tube Lines and LUL have been working jointly to configure the necessary automatic links between Tube Lines' internal project management systems and the MPD. The MPD is not yet a fully functional management tool because the required technical integration and data cleansing has not yet been completed. LUL expects to be provided with a full set of data by Tube Lines by September 2004.
