In the night of March 24, the final engineering train as part of GB Railfreight's ten-year London Underground contract was prepared at Wellingborough Yard. The image above shows GBRf 66718 at work with special headboard at Barking Flyover on March 25. The image below shows the locomotive without headboard after it had returned to Wellingborough Yard with the final train on March 29. Special thanks go out to Richard Gennis for these pictures.
