Noise & Vibration

Control of Noise and Vibration during Construction and Operation of Thameslink Programme

Keeping impacts to a minimum

Twenty-two million people live within 500 metres of our network of which 5 million either back onto or face the railway. Improving our network through delivering major Infrastructure Programmes such as the Thameslink Programme (TLP) will enviably generate noise and vibration. However, if we do not manage these impacts appropriately not only do we have a negative impact on our neighbours but it can also adversely affect our ability to deliver our works, our business and our reputation.

Construction and operational noise and vibration has been our most significant socio-environmental impact therefore as part of our vision to deliver a sustainable programme we committed to implement robust controls to keep these impacts to a minimum.

On TLP we have tackled the complexity of delivering major construction works in densely populated areas of London such as Blackfriars, Farringdon and London Bridge and introduced more trains to our network, whilst keeping our communities impacts to a minimum.

Kings Cross Tunnels track design incorporated Pandrol Vanguard resilient baseplate, which was anticipated to reduce the noise levels by 10-15 dB. Following installation in 2010-11, monitoring was carried out over an 18 month period which showed that the combined benefit of the resilient baseplate and re-railing with micro-head hardened rail reduced the average train noise level by 19 dB (approximately 13 dB is considered to be due to the baseplate).  The new track system also eliminated rail corrugation over the 18 month monitoring period.

Case Study

Noise & Vibration Management: London Bridge station

Examining the robust controls adopted to keep noise and vibration impacts to a minimum during the redevelopment of London Bridge station.

Acoustic Wall: London Bridge Station

Installation of an acoustic wall during the later stages of construction enabled 24/7 works to continue in a noise-sensitive location.
