The June 2020 heatwave seemed to have had an unfortunate effect of DB Cargo's Class 60s, with several failing in traffic. Such was the case on 25 June 2020, when 60015 failed at Theale, prior to working the 6B33 13:35 Murco oil empties to Robeston. I was keeping an eye on proceedings, and noticed that 6B33 hadn't moved, then the unwelcome appearance of 66106, running as the 1Z99 rescue light engine from Westbury confirmed my suspicions. 66106 is pictured here, along with the disgraced 60015, passing Great Bedwyn, running 142 minutes late.
