Model building direct current can be converted to alternating current track by using a device called an inverter. The inverter takes the direct current from the model building and converts it into alternating current, which is then used to power the track. This allows for the model building to be integrated with an alternating current track system, providing a seamless transition between the two power sources. Additionally, using an inverter allows for greater flexibility in the types of power sources that can be used with the model building and track system. **
