A steam engine is basically a method of turning pressurised steam created in the boiler into forwards and backwards motion via means of pistons and connecting rods to the wheels. However, a locomotive such as General Steam Navigation takes the basic principles to create a complex design to create power and efficiencies.
These pages aim to provide an overview of some of the design features incorporated within General Steam Navigation.

The Bulleid boiler design was a highly efficient steam raiser and “generally recognised as the best of all pacific boilers”. Read more about the design here.
The purpose of the valve gear on a steam locomotive is to control the flow, direction and amount, of steam passing into and out of the cylinders, Bulleid's innovative chain drive valve gear is described here.
One of Bulleid’s most instantly recognisable features on his Southern Railway locomotives are his BFB wheels.
Another recognisable feature of Bulleid pacifics was the electric lamps fore and aft and also within the cab. Electricity was generated on board by a “Stones steam generator”.
