Choosing the right model train power supply: DC vs DCC.

Learn how to choose the right power supply for your model trains. This guide breaks down DC vs DCC, their pros and cons, and offers helpful videos to make setup easier.

DC vs DCC: Understanding the Difference

DC (Direct Current) controls a train mainly by changing the voltage supplied to the track. It is a straightforward and familiar choice for many smaller or simpler model railroad layouts.

DCC (Digital Command Control) sends digital commands through the rails to decoder-equipped locomotives. This allows locomotives to be controlled independently on the same powered section of track and can also support features such as lighting and sound.

Which System Is Right for Your Layout?

DC may be a good choice if you want a simple, lower-cost setup or already own DC equipment. DCC may be a better fit if you want to operate multiple locomotives independently or plan to use more advanced sound, lighting, and control features. Your layout size, budget, existing locomotives, and how you want to operate your railroad should all be considered.

The videos below provide additional explanations and examples to help you compare the two systems.
