‘Pacific’, collectively a name applied to steam locomotives with a 4-6-2 wheel arrangement is perhaps more commonly associated with express passenger engines but that is not the whole story, there were also Pacific Tank Engines. The LNER is famously associated with their streamlined Gresley A4 Pacific locomotives and that most celebrated of locomotives, Flying Scotsman. The new build Pacific Tornado has raised the profile of the 4-6-2 type to even greater heights. The LMS produced powerful Pacific locomotives to a Stanier design; whilst the Southern Railway constructed Bullied air smoothed 4-6-2 engines. The GWR, who built Britain’s first Pacific type, actually entered the BR era without a 4-6-2 type on their stock list! However Riddles included 4-6-2 engines in his multi regional BR Standard range. The locomotive specifications are illustrated and presented in a manner which will appeal equally to enthusiasts, model makers and railway historians.
