                                                12. Add a couple more keys somewhere around frames 18 and 50. Lower the second of the new keys
                                                    until the curve is shallower but not horizontal. Again, adjust the train’s position on the track
                                                    (Percent along the path) by raising or lowering the two new keys.
                                                13. Adjust the Out tangent handle of the very first key and the In tangent handle of the very last key
                                                    to produce a smooth looping animation.
                                             Figure 36.11 shows the final curve after you’ve completed the editing, and Figure 36.12 shows the mono-
                                             rail along its path.
