47710 was named Capital Radio's Help A London Child at the Old Oak Common Open Day on 17 August 1991. Four days later it was still looking immaculate when it came to the aid of D400 which had failed prior to working the 1V09 08:40 Waterloo to Exeter St David's Network SouthEast service. The ensemble is pictured here at Stoford. As a result of its failure, D400 was to receive the power unit from withdrawn 50048, even though its current engine had only been in situ for less than a year.
