Author,  I also have experenced the problem of the locomotives jumping the track at the switch.  I tried four different units running first forward than backward.  Each time the same problem.  I also had problems with the switch operating at least 75% of the time.  One would not do anything and the other would just buzz.
   A local dealer told me that I probably should go with a more expensive track.  But I wonder if that is because he would make more money.
   Hopefully someone will be able to help us out.
