Reply to "TRIAC circuit to control PW"

FlashOGR Forum Member

I do know that household dimmer switches will not work for 3-rail 18vac train. I've tried.
That circuit from instructables does not look like it will work for controlling trains. I'm not an electrical engineer so I can't quite explain why. All I can say is that it's doesn't look right.
I've been down your path before and came up empty when searching for DIY circuits. My advice is to buy a MTH Z controller and reverse engineer it or just use it as is. Also you are going to have to figure out a way to limit that 24v transformer to 18v.
Ultimately I just decided to go TMCC all the way and have a 18v transformer brick connected directly to the track.
