My friends asked me a question about Insulation between tracks, I am not
sure if it will be a problem. Base on some expert's idea, we can
insulated tracks using adhesive tape as follow:
                          |----|
+ ===========O======= -
-  ===========O======= +

|----| is motor
=== is tracks
O     is insulation

The problem is when motor is on the two parts of insulated tracks, and
the current is opposite as above, does the short circuit happen? How can
we avoid it?

Never allow it to happen. While for LEGO it's not a big deal, in regular MR,
it is, it can burn out power packs. Make sure you switch your isolated
segment in a way that it doesn't occur (you need an isolated segment which
is switchable, made by a PAIR of gaps spaced some distance apart, not just
one set of gaps)... make sure your isolated segment is long enough to span
the longest train you are likely to want to reverse (or at least the longest
locomotive lashup)
