Yes, DCC works on the same tracks that DC (or AC for that matter) does.

What you'll need is:

• A command station
• A throttle
• A booster

but many manufacturers combine those into one device for beginners, for example the Digitrax Zephyr Express or the NCE PowerCab. I thought Bachmann did also but I couldn't find it on their site.
If you have a local club that uses DCC, you might want to follow their direction and get the same brand hardware so that you have some friends locally that can help.
