CASE STUDY to similarly protect ( through a technology refresh ) the on-going availability of our below-ground data network services that underpin ( and are a key dependency for ) the TETRA radio system . This is what is being now delivered by Thales and Nokia .
How will the renewed multiservices network ( MSN ) specifically improve operational efficiencies and passenger experiences on the Tube and rail network ?
The MSN serves as the underlying infrastructure that supports Connect , Thales ’ industry-leading system responsible for the critical communications ecosystem that underpins the London Underground . This includes radio , transmission and operational CCTV technology used by TfL staff to maintain smooth operations , making the MSN vital to efficiency on the rail network and ensuring a safer and smoother passenger experience .
Having a modern high-bandwidth optical IP network , stretching across the whole of the London Underground , enables a multitude of existing and new services to be delivered . Not only is this efficient through its wider utility , but it is also easier to maintain , support and expand for future use cases , saving money and ensuring a safer and more effective operational railway . For example , with the MSN providing multiutility to the whole underground , it has been designed to allow TfL to ‘ on-board ’ new services as they emerge e . g . future signalling upgrades .
What role does Nokia ’ s mission-critical IP / MPLS network solution play in this renewal project , and how does it complement Thales ’ Connect system ?
The Nokia solution underpins the core infrastructure that makes up the network that will replace the existing Connect networks , where all circuits and services will be migrated across . Nokia is essential in delivering this system and ensuring its safe and reliable support throughout its life .
In what ways will the updated communications network enhance the safety and security of passengers and staff on the London Underground ?
Legacy systems can slowly become unreliable and could disrupt services , leading to delays and an overall negative impact on passenger journeys . Ensuring a data-backed , integrated and timely update – such as this one spearheaded by Thales and Nokia – proactively addresses these concerns , without hampering passenger mobility .
The key service that Connect delivers is a digital operational radio system that provides communication between trains , stations and control centres as well as for engineering staff carrying out projects and maintenance . We have invested to ensure this radio system is supportable for many years to come , however , as mentioned , the networks that underpin this service are obsolete and present a significant risk of failure , therefore the new network will ensure that Connect continues to deliver a reliable radio service , ensuring the safety and security of our staff and customers .
How does this communications renewal align with TfL ’ s broader strategic goals for Digital Transformation and modernisation of the transport network ?
In creating the new multi-service network we have created a significant enabler for all operational transmission needs , both now and in the future . It will become the core operational network for all critical services , for example , new signalling systems , new fleet train data communications , station security and of course , Connect . Put simply , it will allow us to progress our strategy of a digitised railway .
What measures are being taken to ensure the new communications network remains future-proof and scalable to meet evolving demands on the London Underground ?
The solution has been specified with scalability and expansion in mind , as we know emerging requirements will present themselves over the years . We have aspirations to extend the reach of the network into many other operational areas and even begin to connect other TfL modal networks , where there are synergies and present improved safety and operational efficiency and effectiveness . p
IN CREATING THE NEW
MULTI-SERVICE NETWORK WE HAVE CREATED A SIGNIFICANT ENABLER FOR ALL OPERATIONAL
TRANSMISSION NEEDS , BOTH NOW AND IN THE FUTURE .
