Track power ?

[HomeRacingWorld]

You can wire it how you like.

Why negative? Unless you just going to use the standard power base then?

Are you just looking to go variable, or is it more juice that you are after?

Well you are welcome, and I think your choice of a better adjustable supply is a very smart move. Either the MG or Pyramid is the best choices for the money in my book.

When it comes time to move it, there are very easy to follow diagrams for wiring it yourself. if I can do it without starting a fire, I know you can.

If you buy a pyramid, make sure you can get it repaired. Regalman82 bought one and needs service. He has called and emailed with no reply. Lucky for him, he's using my pyramid.

I noticed at least one thread where someone was using a Lionel transformer with their racing set. Is there any reason I could not use a DC train transformer for my track?

Train transformers are not regulated, so you would get power surges, even with a large one.
You can use Parma controllers with either positive or negative wiring. If you are going to use a large power supply the track wiring must be able to handle the extra power, in addition there should be a fuse or circuit breaker for each lane.
Here are the two ways of wiring a track. Negative polarity is the way all set type tracks are wired, the positive polarity method is the way most wood tracks and 1/24th commercial raceways are wired. Many electronic controllers come in positive polarity versions only.





To convert a negative polarity track to positive polarity all you have to do is switch the wires at the power supply and also switch the wires that connect to the track rails.
