British Railway (B, H, J, and L Classes); North Eastern Railway (Class Z); Taff Vale Railway (A class); War Department (ROD 2-8-0). After 1923, customers included the Great Western Railway (5700 class); London, Midland and Scottish Railway (Fowler 3F, Fowler 4F, 4P Compound, Stanier 2-cylinder 2-6-4T, Jubilee, Royal Scot, and Stanier 8F classes, and the experimental Fury); London and North Eastern Railway; (Classes A1, B17, K3, Thompson B1, and Thompson L1); Southern Railway (L1 and N15 King Arthur classes); War Department (Stanier 8F, WD Austerity 2-8-0 and WD Austerity 2-10-0 classes). Locomotives 22878, 22879 and 22880 In 1922, the New Zealand Railways Department ordered a batch of its very successful AB class Pacifics from NBL, to be built and shipped as soon as possible. The trio 22878, 22879 and 22880 were built amidst this batch. 22878 and 22879 were loaded aboard and she sailed for Auckland, New Zealand, but she got into difficulty at Rosalie Bay, on the east coast of Great Barrier Island and sank. Remnants of both locomotives, and the Wiltshire can be seen on the sea floor. 22880 was dispatched on a subsequent sailing and was put into service in New Zealand as AB class number 745. This locomotive was in service for more than 30 years but then hit a washout near Hawera. It was then left in the mud for nearly 50 years but has now been exhumed with the intention of restoration. It was moved to the nearby town of Stratford, New Zealand for preservation by Taranaki Flyer Society. Due to the TFS headquarters being sold from under them, 22880 was put on the market, and has been taken into storage by Rimutaka Incline Railway Heritage Trust, after the Taranaki Flyer Society was liquidated in December 2013. Diesel locomotives Whilst highly successful as designers and builders of steam locomotives for both its domestic market and abroad, North British failed to successfully manage the transition to diesel and electric locomotive production in the wake of the British Railways 1955 Modernisation Plan. It did build a Paxman engined diesel locomotive, British Rail 10800, originally ordered for the London, Midland and Scottish Railway before the 1948 nationalisation of British Railways, but not delivered until 1950. This was closely followed by eight Bo-Bo diesel-electric locomotives for the Ceylon Government Railway (CGR class G2). Another Paxman engined locomotive was PVH1, built in 1953 as 'Paxman Voith Hydraulic 1' (hence
