Remove the 'C' and then...bring it back to start! As you can see, the letters A, B, and C. The key word to keep in mind here is tracks. In this puzzle you are trying to free the C from the AB piece. Taking the wrong route will lead to a dead end, so to speak. Based on a puzzle that came out back in 1911 in England, this puzzle has a lot of history behind it.
