The Fascinating Inner Workings of a Steam Locomotive

TLDRLearn all about the steam locomotive, including its firebox, boiler, pistons, and brakes. Discover the art of steam power generation and the unique features of the Union Pacific "Big Boy" locomotive.

Key insights

🚂Steam locomotives use coal, wood, or oil to generate steam power.

🔥The firebox is where fuel is burned to produce heat for boiling water.

💨Steam expands and pushes pistons, which drive the locomotive's wheels.

🔧The valve gear controls the timing of steam delivery to the cylinders.

🚂The brake system, powered by compressed air, slows the train.

Q&A

What is the purpose of the firebox in a steam locomotive?

The firebox is where fuel is burned to produce heat, which boils water to generate steam.

How do steam locomotives generate power?

Steam locomotives generate power by converting the energy from expanding steam into mechanical motion through pistons and drive wheels.

How is steam delivered to the cylinders?

Steam is delivered to the cylinders through a valve gear system that controls the timing and quantity of steam.

How do steam locomotive brakes work?

Steam locomotive brakes work using compressed air to apply pressure to brake shoes against the wheels, slowing the train.

What is the 'Big Boy' locomotive?

The Union Pacific 'Big Boy' locomotive is one of the largest and most powerful steam locomotives ever built, known for its 4-8-8-4 wheel arrangement.
