TFL - Earl’s Court Communications Upgrade

Contract Value –  £2,500,000

As part of the Station Stabilisation Project (SSP), Delatim were contracted by London Underground’s STAKE division to undertake the Communications upgrade works at Earls Court Station.

The Communications Package was bespoke to Earls Court station and included a number of technical elements that were being implemented for the first time on the underground network, the finest example of this was a hybrid PA/PAVA system to mitigate the long standing noise abatement order that was issued from the last PA upgrade in excess of 10 years previously.

Delatim were also closely involved with the clients engineering team and stakeholders, this allowed third party interfaces to develop, thus ensuring systems were brought into use with minimum disruption to the operation whilst maintaining full use of both the new and existing systems during the trial running prior to BIU.

Delatim undertook the detailed design in accordance with LU’s extensive assurance process producing compliant submissions and detailed CAD information to ensure that the system was both functional and buildable prior to the system going to site for construction. This was largely achieved by constructing a representative solution at our office facilities to configure and demonstrate the integrated systems and the bespoke interfaces prior to it going to site for construction. This provided a high degree of confidence that no major defects were prevalent and that the proposed testing regime was sufficient to bring the integrated system into use.

Works included:

  • PAVA
  • Data Networks and Fibre Back-bone
  • IP CCTV surveillance and recording system
  • Master clock and slave units
  • Commend Help Point
  • Passenger Information Displays
