How does a steam engine start?
When heated, water turns to an invisible vapor known as steam. The volume of water expands as it turns to steam inside the boiler, creating a high pressure. The expansion of steam pushes the pistons that connect to the driving wheels that operate the locomotive.

Why do steam locomotives chug?
Each ”chug” is the noise made by escaping steam as the engine’s valve gear releases steam at the end of one stroke of one cylinder. For example, in a two-cylinder steam locomotive, the connecting rods turn the driving wheels at one revolution per complete cylinder cycle.
