King’s Cross Train Station


Acoustics Plus were contracted by the communications company working on Network Rail’s £500 million redevelopment of King’s Cross to design and test a new public address and voice alarm system.

King’s Cross station is one of the busiest in the UK and struggles to cope with its 40 million-plus passengers a year – a figure set to increase. The redevelopment will address this problem, transforming the entire station by 2013. By the time of the 2012 Olympics, there will be a new concourse and an improved interchange with St Pancras International.

The brief

  • Design the public address and voice alarm system for the new western concourse, train platforms, and train sheds

  • Carry out an acoustic computer modelling study to verify that the proposed acoustic design will meet the acoustic design criteria specified in the performance constraints

  • Parameter prediction including reverberation time, sound pressure level and speech transmission index

  • Post commissioning electro-acoustic performance assessment of intelligibility and sound pressure level.

The acoustic design had to work within constraints dictated by the listed status of buildings at King’s Cross Station.

The results

  • PA-voice alarm system for new western concourse scheduled to be installed by 2012.

  • Platform PA-voice alarm system currently being installed
