Your intelligent video team

We created AIVR – Trailblazing rail monitoring technology.

There are many benefits to our AI-powered remote monitoring technology which is trained to highlight priority issues within engineering and safety across the railway.

Largest Rail Video Data Platform with Integration Capability

AIVR hosts over a petabyte of footage captured across the breadth of the UK rail network, making it one of the largest train video data archives.

Thermal Imagery

AIVR Thermal records high-resolution infrared video footage along the conductor and running rail to provide you with a comprehensive overview of the condition of the track. AIVR Thermal uses advanced Machine Learning capabilities to ensure high temperature areas – ‘hotspots’ – are automatically identified within the platform to alert users to potential faults in rapid time.

Artificial Intelligence / Machine Learning

AIVR enables training datasets to be created which in turn allows crucial information or potential issues to be easily identified through Machine Learning and AI. Our approach involves working closely with rail experts and end users to build this capability to provide insight and solve real world challenges.

What our partners say about us

"A fantastic example of use of trainborne technology to improve performance & intervene before failure, and in such a critical area; well done to the project team working on thermal imaging."

Network Rail

Infrastructure Director

"Great solution that’s enabled early planning of work sites in a controlled space prior to going trackside - reducing exposure to the railway environment and improving site knowledge."

Siemens

Construction Manager

I live in North Yorkshire, in less than 5 minutes I can be in London, or Cornwall, or Scotland, viewing high-resolution videos of sections of track I would otherwise have had to visit in person to perform the same visual checks. It’s an invaluable and easy-to-use tool.

Schweizer Electronic

Matt Handford, Training & Technical Support

"Great solution that’s enabled early planning of work sites in a controlled space prior to going trackside - reducing exposure to the railway environment and improving site knowledge."

Construction Manager

"AIVR has helped me with signal sighting activities on a number of schemes, where alternative footage was not readily available."

VolkerRail

"The AIVR technology has evolved rapidly to give us real-time insight on the network to aid planning and maintenance, to keep our colleagues safer and trains on the move."

Network Rail

Wayne Cherry, Senior Innovations Engineer

"We have found the AIVR software really useful and a great tool to assist us with our Signalling Design projects!"

DigiSig Rail Group

Russell Simpson

"GGP find the AIVR system to be a useful and user friendly tool for both increasing our pre-site survey spatial awareness around proposed assets and obtaining a base understanding of the lie of the land for our many long linear projects."

GGP Consult

Euan Allison, Principal Civil Engineer

"AIVR is a good tool for Access Point work, such as identification of track entrance Stairs and Platform ends. I have used AIVR to support already collected data with further verification confirmation."

Network Data Manager

"It really is a massive benefit having such a vast coverage of cab footage without the hassle of having to arrange track access and often drive hundreds of miles in the process."

QTS

Barry McLeish, Operations Director

"AIVR by One Big Circle has enabled our planning and site teams to gain a better understanding of site conditions and layout before attending the location due to the availability of regularly updated high quality footage."

Kier

Anthony Brooks, Senior Planning Manager

"An excellent tool in assisting in preparation of tenders and for detailed planning upon contract award."

S&T Cover

"Ease of use and an extensive video library made for rapid deployment of this tool to the project teams. Gives an up-to-date window view into project environments."

Siemens

Project Manager

"I am involved in 11 signal sighting projects and in the last 18 months I only visited site once due to the clarity of the footage on AIVR."

Signal Sighter

"….this is an Ideal tool, points out everything in the site that could be a hazard, and can be used to aid the site briefings too."

Story Plant

"We think it is a great tool and really helps us with our planning – we are just scratching the surface of using it “properly,” I think so expect to get more value as we go."

Kent Group

Robert Kent, Operations Director

Senior Planning Manager

"[AIVR] solved two problems we had at once; it enabled colleagues to plan better and negate the need to go lineside [and] whilst COVID restrictions were in place, it replaced the need to undertake mandatory cab-riding inspection on scheduled services"

Network Rail

Route Director, Nick Millington

"We find the AIVR system to be a useful and user friendly tool for both increasing our pre-site survey spatial awareness around proposed assets and obtaining a base understanding of the lie of the land for our many long linear projects."

Principal Civil Engineer

"AIVR has become an essential component of our POS planning process."

Shovlin Plant Hire

Gaby

"AIVR gives us 100% visibility from each site, whereas before we'd be lucky if we were to see 50% of the site."

Story Plant

"Its been a great tool for me to use and has saved on having to carry out site visits all of the time and with more and more videos being added there is good choice most of the time when looking at a specific area."

QTS

Jamie Mcllvaney, Isolations Manager

"Very good equipment to have to give us a heads-up before the patrols are due as some of these faults may not have been seen for a few months until the patrols are completed. I can now plan ahead and get the faults checked and the work completed before it effects the running of any passenger train."

Network Rail

Section Supervisor CRE

"We feel that we have plenty to offer on this sustainability journey and AiVR is certainly part of that ability to reduce our carbon footprint."

Ramboll

"It really is a massive benefit having such a vast coverage of cab footage without the hassle of having to arrange track access and often drive hundreds of miles in the process."
