Here’s the layout: an oval with a left and a right hand turnout. The turnouts
turn into the oval and are connected with track. Nothing complicated here.
If I switch both turnouts to the inside I get a short. If I switch only one
to the inside and keep the other straight and there’s no short. In other words
if the train is switched inside it will continue to run as long as the other
switch is straight (no turn in). Ultimately of course the train will hit this
switch and derail -- so at some point the ‘receiving’ turnout has to be
flipped to receive and then there’s a short. Is this the way it is supposed to
work? I don’t think I’ve got a reversing loop here. The turnouts are new.

If you’re getting a short, then you have a reversing loop. I’m guessing it looks
something like this:

If so, you definitely have a reversing loop. You can work around it by
insulating the inside section of track completely and controlling it separately.
But the easiest way is to drive the train onto the inside section, then flip the
“entry” point back to “straight” (isolating the inside section completely),
flipping the “exit” point to “curve”, and driving the train out. And you will
see when you do, that the train is now traveling the opposite direction.
BTW, running a train over a point set the wrong way should not derail the train
- LEGO points are spring loaded to allow this.
Hope that helps.

| (...) Rosco, Thanks. Maybe it is working the way you describe. But in your diagram you have two left hand switches. I have a right and a left so my diagram would make the internal track look like an upside down 'V' rather than a diagonal slash. If (...) (19 years ago, 7-Jun-05, to lugnet.trains, FTX)
