Soldering wire directly to track

Don’t give up soldering, put the heat to it, it’s very simple and almost always works well. It’s just not that big a deal. Jake

John YES I use it on all my soldering the pack shows that is a lead free solder powder and active flux I get it from Brennan’s

I have had great luck soldering to my Nickel Silver Atlas track. Then I hit a stretch on an uphill grade where I had used stainless steel (hoping to aid my Magnetraction Locos) and I could not solder at all. Was I trying something impossible, or was I impossible poor at trying something that should be possible?

Thanks, Sandy
