The system, which is now live, uses 3D analysis to automatically recognise and monitor a variety of pantograph designs operating on the same network. The system records wear-and-tear in order to anticipate any issues that may arise in future, as well as providing instant alerts to the train operator.

Camlin Rail says tshe lightweight modular design also simplifies the installation process and reduces lifecycle maintenance costs.

The Heathrow Airport line is currently used by up to 186 services a day.

“Providing frequent, reliable and sustainable access to the airport is critical to Heathrow’s success,” says Heathrow Airport head of rail, Mr Mark Chestney. “Rail is fundamental to this today and will be even more so in the future as Heathrow encourages both passengers and colleagues to move away from using cars and into the use of public transport, for the improvement of local air quality. Pantobot 3D will help achieve our transport ambitions, and will provide us with crucial tools to help us prevent and react to damage that could impact passenger journeys.”
