When Holden introduced his oil-burning equipment, Nos. 712 and 759 to 767 inclusive were fitted with it, and their tenders acquired on top two cylindrical tanks, arranged longitudinally, to accommodate the oil fuel; No. 760 received the name Petrolea in honour of this change. Nos. 762 to 767 and 1030 to 1039 also had their tenders fitted with water-scoops in preparation for the non-stop running over the 130 miles between Liverpool Street and North Walsham of the summer Cromer Express (later the Norfolk Coast Express), which began on 1 July 1897, water-troughs having been laid down both at Halifax Junction, Ipswich, and at Tivetshall St. Mary for this purpose. The engine chosen for the inaugural run was No. 1037. However, oil burners were progressively discarded by the Great Eastern Railway due to the additional fuel costs.
