Electrification of Great Western route

Ricardo Certification provided a key role in one of the largest ever electrification upgrades in the UK

Completed in January 2020 authorisation for use was granted by the Office of Rail and Road to open the final - and most westerly section - of the newly electrified Great Western route.

The route is one of the country’s busiest, providing passenger and freight links from London’s Paddington station to the south west of England and southern Wales. But it is also one of the oldest, following a pathway first established in 1835 by the famed engineer, Isambard Brunel. 

In 2010, Network Rail embarked on a £7.5 billion modernisation programme to revamp the railway, installing infrastructure to support faster and more reliable services for the region.

A key foundation of  the scheme was the 235-mile electrification between London, Oxford, Newbury, Bristol and Cardiff. In addition, new electric and bi-mode trains, track upgrades and station improvements were part of the scheme. 

Ricardo Certification was appointed by Network Rail as the Notified Body/Designated Body (NoBo/DeBo) for the assessment of compliance with the Railway Interoperability Regulations (RIR). The scope encompassed the mainline between Maidenhead and Cardiff and included assessment of compliance with the current Technical Specifications for Interoperability (TSI) for the Energy, Infrastructure, Command Control and Signalling, and Persons of Reduced Mobility Sub-Systems, for the 25kV electrification programme and related infrastructure projects. Separately, Ricardo Certification continues to act as the NoBo/DeBo for the Maidenhead to London Paddington section for Network Rail’s Crossrail project. 

Over seven years our teams logged, processed and, where appropriate, assessed more than 10,000 reports, drawings, certificates or supporting compliance documentation. Our final pre-authorisation deliverables included AsBo Safety Assessment Reports, NoBo/DeBo Technical Files and various addendum's, with the final deliverable submitted to the client on schedule in early January 2020.
