Southeastern is fitting thermal imaging cameras to the fronts of more of its trains following a trial that used them for live track inspections. Earlier this year, a pilot programme installed thermal imaging cameras on the front of a small number of Class 707 'City Beam' trains. They successfully identified 41 overheating incidents and prevented over 150 hours of customer delays. The thermal imaging cameras can identify 'hot spots' on the rail network and relay this information rapidly to asset engineers.
