66523 leaves Moreton-in-Marsh on 10 November 2016 with the 3S33 05:56 Swindon to Gloucester Horton Road Rail Head Treatment Train, having arrived a little earlier led by 66513. The Freightliner locos had been hired in by Colas, as due to the failure of both 56078 & 56104 three days earlier, they had run out of locos! This pictures makes an interesting comparison to the same scene a week earlier, when Colas could rely on their vintage Type 5 traction!
