Multitrack maze type 3

Multitrack maze type 3 (single station, multiple closed tracks) contains only one station inside the maze, graphically represented by a token such as a star, etc. The solution consists of drawing N (typically three) completely separate tracks through the valid paths of the maze, so that each track begins and ends in the station.

Here is an example of a Type 3 multitrack maze with three closed tracks:
