London Underground track renewals contract

Balfour Beatty is delivering essential works to upgrade the 1,047km of underground network that keeps London moving.

To ensure the continued reliability of the London Underground network, the contract will see investment in critical assets and the delivery of strategic enhancements. This includes the renewal of 13 kilometres of ballasted track and associated drainage, signalling, traction power and rail conductor works.

We were first appointed to deliver track renewals on behalf of Transport for London in 2010, with the contract extended in 2019 for an additional four years.

Our detailed knowledge and experience of London Underground’s infrastructure and systems, as well as our commitment to championing innovation, was instrumental in securing the contract.

Throughout the programme of works, we will introduce new measures and technologies such as remote surveying systems and viewing software to generate significant efficiencies while continuing to safely deliver the highest standard of work and reducing any potential disruption to the travelling public.
