On the 5th December 1977 55014 (D9014) "THE DUKE OF WELLINGTON'S REGIMENT" waits at Darlington with the 1E20 15:00 Edinburgh - King’s Cross "The Silver Jubilee" service. It is unknown when the use of a headboard ceased on this service, however, the title was certainly dropped by the start of 1978 when both the 1S12 07:45 King's Cross - Edinburgh and 1E20 return were handed over to HST.
