The set includes a way to power it by attaching a Lego Power Functions (PF) Motor to the firebox, the motor being concealed within the Locomotive's cab. This motor, while running, would turn an axle which runs the gearbox and power the drive wheels. The design of the gearbox keeps it hidden behind the set's details, and also speeds up the normally slow rotation of the PF Motor. The wheels that are powered by the motor are only the two back drive wheels, out of the six of them.

The gearbox of the Emerald Night.
The bright yellow gear that's sticking out rotates a smaller
gear, speeding up the rotation of the axles. |
The simplicity of this gearbox is quite admirable. As this uses a simple law of
Gear Ratios, it can be used in other creations by anyone!
