Larger diameter cylinder
- Steam locomotive power is also related to cylinder size and shape. A larger diameter cylinder will provide more power than a small one. A large drive wheel needs a cylinder with a longer stroke, which — all other things (such as steam volume) being equal — means a smaller cylinder diameter, which also means less power.

The cylinder is the power-producing element of the steam engine powering a steam locomotive. The cylinder is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder.
May 22, 2017 · In the UK, the issue is the restricted loading gauge. Two cylinders would be too big in diameter in more powerful locos (class 8+) to fit in the platforms etc. That's why the Duke had 3, and Brits 2 cylinders, and the other class 8P locos 3 or 4.

Aug 21, 2021 · Lower or higher output RPM is produced using gears. A simple steam engine has no compression or ignition, and its RPM is determined by how fast steam is introduced into the cylinder. With a large bore cylinder and slow steam intake, RPM can be as low as you like.
Oct 3, 2023 · The design of the cylinders in a steam locomotive engine is critical to ensure efficient power generation. Factors such as the size and configuration of the cylinders, as well as the arrangement of multiple cylinders in locomotives, impact the force and speed at which the pistons move.
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed by a connecting rod and crank into rotational force for work.
