CircoSense installation at Abellio Scotrail’s Shields Depot


Shields Depot, located in Glasgow, is a railway Electric Traction Depot which uses state-of-the-art technologies to maintain Abellio Scotrail’s electric trains.

The company have worked hard to reduce their environmental impact, and have established environmental targets for energy use reduction and reducing landfill waste.

In order to reduce energy at the Shields Depot, Abellio Scotrail decided to undertake a “Proof of Concept” installation of the CircoSense3000 device, which uses cognitive technology to learn usage patterns of hot water systems, turning on the circulation pump only when required. This then leads to lower energy bills and a reduction in carbon emissions through the reduction of circulation losses.


Campbell & Kennedy was appointed to install the unit in September 2016 within the Maintenance Building 1, and as part of a “Proof of Concept”, underwent a 6-week trial to prove the savings which could be achieve at this particular site.


After the trial period concluded, it was established that the CircoSense3000 had resulted in savings of 40.14% on the cost of heating hot water at the site.

The CircoSense3000 also reduced carbon emissions at the site, with a reduction of 12.4 tonnes per annum.

Martyn Savage, Technical Director of CircoSense, stated

“Our Proof of Concept trial within the Maintenance Building 1 at Shields Depot has proved extremely successful, resulting in significant savings for the client, both in carbon emissions and in energy bills. We look forward to continue to work with Abellio Scotrail and discover if there are further sites within their estate which CircoSense could help to reduce energy bills.”

David Park, Environmental Manager at Abellio ScotRail said

“We decided to trial the CircoSense3000 to see how much our energy bills could be reduced at Shields Depot. Following the trial, we were delighted with the level of savings which the device achieved for us.”
