Locomotive Piston

We just learned about the Piston Rod.

Another part of the Locomotive is the Piston.

This is the thing that pushes and pulls the piston rod, using the power of the steam.

Remember we've learned about how hot steam pushes out, and then cooling the steam makes a vaccuum that pulls or sucks in.
- The pushing and pulling of the steam and vaccuum is pushes and pulls this piston
- The piston pushes and pulls the piston rod
- The piston rod pushes and pulls the connecting rod
- The connecting rod spins the train wheel around
