Hello,
this is my first post to Lugnet.

Hi and welcome! (I have to ask, out of curiousity and nothing else, what’s
up with the transposition on your name vs. posting name though, there has to
be a story there.. I noticed it when I approved your posting setup recently)

Maybe this is common knowledge in Lego train community, but I have never
seen mentioned that points can be used as insulated tracks. Here is an
example of reversing loop with standard Lego parts:

You don’t need to break your tracks for reversing loop project and this
loop type takes only one of your straight tracks which are often needed
elsewhere.

Doesn’t this have the possible flaw that if you set both turnouts to route
in the loop direction that you could still get a short?

Hello,
interesting design and quite simple, but like Larry pointed out, no matter
what is the position of “A”, if you set “B” to turn, you get a short. Leave
“B” to strait amd when a train come to “B”, it will push the alingment to
pass and stop after the motor cross.
|
That, as I see it, is the idea. The point B is always set straight. There may be
momentary short(s) when the motor pushes it to curve to pass, but once it is
past and stops, switching A then supplies it with current, now in the opposite
direction, thus the train continues out of the loop.
You have to be careful that the train always enters with point A straight though
:) And you also have to make sure there is enough length between A and B to
allow for trains with multiple motors.
