I had a piece of balsa that I pushed into the track, then cut out two deep 'tranches' for the rails to sit in where it had been marked. Then, I mark where the track has to be cut, put the jig just before it and saw through with a small tenon saw. The end sometimes needs tidying up with a needle file, but most times it's OK.
I have also used a Dremel off eBay for £20, but one of the discs flew off and almost took my eye out
