David Waboso CBE, managing director of Network Rail’s Digital Railway programme, has announced that he will retire in March, the same month in which he turns 63.

He joined Network Rail in 2016 from Transport for London, where he had been director of capital programmes, delivering a catalogue of major tube upgrades.

Announcing David’s upcoming departure, Network Rail chief executive Andrew Haines paid tribute to his work, saying: “Through his skilful leadership and passionate advocacy, Digital Railway is now becoming a reality on ever growing sections of our railway system.

Network Rail chairman Sir Peter Hendy (right) has called David Waboso “one of the most talented project engineers in the world”.

“He leaves a fantastic legacy of a clear direction for delivery through CP6 and beyond, integrating track and train to deliver benefits for passengers and freight users.”

The former maths teacher originally obtained degrees in civil engineering from Coventry University and Imperial College London. After a spell of teaching in east London, he worked on water supply and transportation projects in Nigeria.

Joining the Nicholas Group, David project managed the Docklands Light Railway block resignalling upgrade. He was also instrumental in the integration and commissioning of the Jubilee line extension for its millennium opening.

Sir Peter Hendy, chairman of Network Rail, has described David Waboso as “one of the most talented project engineers in the world” and “a giant in his profession”.

A further announcement on the transitional arrangements and his replacement will be made in due course.
