There are approximately 50 pantograph (an apparatus mounted on the roof of an electric train to collect power through contact with an overhead line) related incidents in the UK each year. These cause cancellations of passenger services, damage infrastructure, reduce safety and reliability of electrified train operation and have huge financial implications (tens of millions of pounds per incident) for both train operating companies and infrastructure managers such as Network Rail.

A lack of real-time information about pantograph operation and being unable to regularly inspect the infrastructure to inform data-driven decisions currently costs Network Rail around £530 million per annum.

Miodrag VidakovicSolution:

Sentech Analytics Ltd has developed a new ‘smart-pantograph’ system: a multi-parameter, patented and field-evaluated optical fibre-based sensor system integrated with video information, to inform better data-driven maintenance solutions. This system allows users to create comprehensive inspection reports (required by the regulatory bodies) and reduce maintenance costs by providing real-time insight on the status of infrastructure and railway pantographs, preventing costly incidents while reducing maintenance and service outages.

Recent work with Network Rail on the Great Western Electrification programme illustrated this, and the smart pantograph now facilitates faster, more environmentally friendly passenger journeys between Bristol and Cardiff.

The company’s plan moving forward is to get detailed understanding of the challenges faced by the main stakeholders (within the UK and EU), to secure a pilot project and establish appropriate business models for two different market segments: train operating companies and infrastructure managers.


  • 2012 – 2014: UKRI – Instrumented railway current-collecting pantograph grant (~ £95,000).
  • 2016: £180,000 support from Faiveley Brecknell Willis.
  • 2018: £1.5 million grant from Innovate UK.
  • 2018: £25,000 Enterprise Showcase Award.
  • 2020: Enterprise Fellowship from Royal Academy of Engineering.
  • 2020: £50,000 from D.A.T.S. Ltd for Midland Mainline dynamic testing (Commercial contract).

“In this very short period of time, the training provided by the Royal Academy of Engineering has been very important for my personal development as well as a great guidance on how to establish the company. In addition to that, having regular conversations with staff and my coach has been very helpful to get answers to a number of dilemmas.”
