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?

| The scenario you are proposing in indeed a problem. It happens commonly when using block control or reversing loops. A couple sugguestions: 1. If you are using block control, then create shorter blocks and adopt a rule that no two trains can operate (...) (23 years ago, 13-Mar-01, to lugnet.trains)

| (...) You can't. But, as long as it is not the exact same distance between the 2 rails and the power supply, the motor will still see a difference, and likely move. If it doesn't, get out your handy HOG and push it off the joint, and watch it fly (...) (23 years ago, 13-Mar-01, to lugnet.trains)

| (...) I have used electrical insulation tape and it worked fine. You do have to trim it carefully to avoid snags. I had considered cutting off the metal coating to create a permanently non-conducting element but since the tape worked I decided (...) (23 years ago, 13-Mar-01, to lugnet.trains)

| Base on the discussion, I think we can use Insulated Track Components in block control or RCX control, especially in RCX control, if your program has a bug, it is easy to lead to short circuit, I designed all Insulated Track Components, you can find (...)

| (...) 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 (...) (23 years ago, 14-Mar-01, to lugnet.trains)

| After I used successfully insulated tracks as below in my RCX Controlled Train Projects, I found a little problem, the train has to be run in higher speed, or it will be stop at insulated track. |---| +========O=====O===...===- (...) (23 years ago, 22-Jun-01, to lugnet.trains)
