Resonate Group

The company was formed from the Rail business of AEA Technology plc which was acquired as part of a secondary private equity portfolio sale to Vision Capital in 2006.

Resonate Group has been accredited as a notified body and an Independent Safety Assessor in multiple countries, including the UK and the Netherlands.

[9][10] During the early 2010s, DeltaRail Group had responded to British national railway infrastructure owner Network Rail's traffic management programme, but it was not shortlisted in favour of larger overseas competitors; this decision was controversial as DeltaRail's bid had been roughly £1 billion cheaper, as well as involving a shorter timeframe, to deliver.

Nevertheless, by June 2016, with the programme underperforming, Resonate Group was reengaged in the process and, at its own expense, conducted a trial deployment of its system to prove its cost effectiveness and readiness for operations.

[14][15] The company has been involved in various parts of Network Rail's Digital Railway initiative, such as the development of a new timetable editor and other traffic management systems.
