The electronic speed controller has two rotary knobs with which a circuit can be controlled. The two dials can be used to control trains forwards and backwards, the regulator has a central zero position. The speed controller also has four on/off buttons with which four continuous current outputs are switched. LEDs can be connected to them, for example, and their brightness can also be dimmed via a potentiometer which is also included.
A battery compartment for a 9 V block battery is included in the scope of delivery. This allows Z-gauge locomotives to be operated on the move and on the road without the need to connect a plug-in power supply unit (Attention: not suitable for N-gauge locomotives!).
