We just learned about the Brake Hose.

Another part of a steam locomotive is the Blastpipe.

Remember we learned about the firebox where the coal burns, and the boiler where the water heats up and makes steam.

For the fire to keep burning, it needs fresh air.
The blastpipe is connected to the boiler and the firebox and the chimney.
When the boiler lets off steam, it helps pull air through the firebox, and then all of the smoke and steam goes shooting out the chimney.
