			were treated to a glass of champagne. On arrival at Newcastle the 
			train's crew were presented with travelling alarm clocks and the 
			driver received an extra bonus of a large cigar! The 1A07 07:35

 17.10.77
 During the week commencing 17th October 1977 unofficial industrial 
			action led to the removal of Deltics from all ECML workings. Action 
			was taken by maintenance staff angry at the proposed closure of 
			Finsbury Park Depot with the introduction of the new HST fleet, 
			which was to be maintained at the new Bounds Green Depot. 
			Maintenance staff 'blacked' the Deltic fleet thus all engines 
			remained 'laid-up' at various installations until the dispute was 
			settled on October 21st. A list of how the dispute affected the 
			class is as follows:
