Welcome tabtas. 
Most hobbyists tend to make their tracks using a hand held router, so freely available CNC files aren't very common. There are commercial track makers that use CNC but of course they don't make their files available.
But I wouldn't have thought it would be too difficult to produce your own, or perhaps get your students to do it, as a learning exercise. All you'd need would be three or four equally spaced lines to cut the slots for each lane. If the track needed to spread out over more than one board, you'd obviously need to divide up the drawings, and if you wanted to cut out the track shape you'd need two more lines to cut out the inside and outside of the track.
If you need any ideas, you could have a look in our routed track plans section, or in our members' tracks section, and if you need any advice on track design then there are plenty of knowledgeable people here on the forum.
