What is the FCC4?

The FCC4 fast clock controller runs up to 15 clocks at speeds of 1:1 to 16:1.

Replace the existing mechanism (called a "movement") with a modified mechanism in clocks you have, buy, or build. You can modify movements yourself, or order them already modified and ready to use.

Connect a 9V DC power supply to the FCC4, and connect the FCC4 to clocks around your layout.

Connect two switches and a pushbutton for full control over your clocks.

Install the FCC4 beneath your layout benchwork or mount it in a control panel or plastic project box.

That's all it takes to add fast clocks to your model railroad!
