South Eastern Railway to Expand Thermal Imaging Trial

The South Eastern Railway has announced the expansion of its thermal imaging camera trial to a set of 20 additional Class 375 ‘Electrostar’ Main Line trains serving South-East London.

First introduced on a set of 12 Class 707 ‘City Beam’ trains; the pilot programme has seen the installation of thermal imaging cameras on the front of the trains which aim to provide real-time monitoring and improve performance across the network.

The technology for the pilot has been provided by AIVR tech company One Big Circle, with tests thus far successfully having spotted 41 overheating incidents and prevented more than 9,000 minutes worth of delays to customers.

Cameras identify ‘hot spots’ on the rail network and then relay information to asset engineers, who then review the data and make a decision on whether the issue needs immediate repairs, ensuring issues are resolved before they cause any disruption.

The technology is also capable of assessing the condition of the railway to determine the correct equipment needed for repairs, as well as the right staff needed to carry out the work without the need to visit the location itself.

Emily Kent, Director of One Big Circle, said:

It's been fantastic to work with South Eastern Railway to deliver this cutting-edge technology onboard the fleet. The can-do spirit and collaboration of all involved has ensured faster, more effective outcomes that will bring real benefits to passengers and staff across the network.

In addition to their front-facing cameras, five of the units will also be fitted with cameras underneath the body of the train. These cameras will monitor how slippery the track is, as well as the overall condition of both the ‘shoe’ and conductor rail.

Rail Minister Lord Peter Hendy said:

This Government is fundamentally reforming how our railways are run, creating a network that works better for the people and freight using it.

The cutting-edge technology South Eastern Railway is installing on its trains is key to achieving this and should serve as an example of the kind of smart investments we’re making as publicly owned rail companies work to improve services.

These upgrades will prevent disruption and reduce delays, supporting local jobs, growth, and housing as part of the Government’s plan deliver an efficient and reliable railway.
