If made from wood, yes they can and do break.  On the first TTS (T005)
I didn't have any breakage but on my second (T040) I had breakage.  I
attribute the non-breakage on the first tracks to a couple of
factors.  First, it was a tensioned friction drive design and the
teeth didn't get that far out of the wheels, and second, the
construction was all Maple (one of the strongest hardwoods).  The
second set had several broken teeth after it's first battle.  This
track was running with an active suspension which allowed the guide
teeth to leave the wheels much farther than a tensioned design which
offers the opportunity for more stress on the guide teeth.  The setup
also built partially from 1/4" aircraft grade plywood which tended to
tear at the first veneer line where the broken guide teeth where
attached.  I solved the problem by driving wood screws from the
outside of the track up through each guide tooth.  Haven't had a
broken tooth since.
