All, Over the Thanksgiving holidays, the Kansas City Southern Railroad demolished a Buckminster FUller designed geodesic dome in Baon ROuge, LA. The dome, 384...
I am trying to help a friend with his O scale layout but I am not sure how 3 rail track works. On a reverse loop he has a problem. I am assuming that the...
... Weird. Reverse loops are usually dead simple in 3-rail. Seem to recall center rail is common, and both outer rails are powered to same polarity. May be...
Hello, everybody! I agree with Jacques. One wire to the center rail and the running rails go to the other side of the power supply. But, if the switch is the...
... In Lionel's convention - which is normally used in 3 rail - the outer 2 rails are normally tied together, and serve as the ground. The center rail is...
My 5 pence worth In the early days of 3 rail you could run two trains in differant directions on one section of track, so the centre was common and the outside...
... That was the Trix Twin system. IMO it was a bit of a gimmick. My friends who had it kept crashing. Most 3-rail systems like Hornby Dublo didn't do that. ...

That's Gravity I'm afraid, not a lot you can do about it... As others have said, the centre rail is at one polarity, the outside ones are at the other. It...
Hello, everybody! A rheostat is an adjustable resistance, so you can make it suitable to your situation. Marx made them, too. Memory says they show up...
My pennies worth. I worked for the importer of Trix Twin in the United States, Polk's Model Craft Hobbies. I also worked for Hornby Dublo in Great Britain....
Thought I might show the group a little pet project of mine. An On30 mini layout. It's a bit of a caricature, but I'm just doing it for fun. I've posted a...
A reverse loop on O scale should be no problem. The two outer rails are the feeds(they are connected together as the ties are metal and are not insulated)....
... Very nice! A little iMovie going on, a little "For a few dollars more" music. Good stuff. I'm building a variation of "Lesser Titchfield" on a 2'x4'...
... To do this, you would first have to insulate all the wheels on one side of the train (not just the loco) I suspect this would cost several times the value...

Hello everyone, I wanted to let you all know that I've started a new model railroad blog, and, as there hasn't been a great deal of discussion here about ...
If my memory is correct (so don't take this as 'gospel'), resistors don't function the same with AC motors, so a variable transformer is used to change the...
I'm wondering, being an electrical klutz, that if you insulated the one rail on the downward slope at both the top and bottom of the slope and feed it from the...
That wouldn't work because most 3-rail wheel sets aren't insulated. Since the wheels on both sides of the train are electrically tied together, and since...
