I'm setting up some two rail Atlas 40" flex track. Just slid together and nailed down to cork the engines lose power totally after around six sections and then shut down. I figured this might happen and am now left with a few choices.
First, I could solder the sections together but that binds me to a layout that I'm just freelancng for now. Very tough to disassemble.
Second, I have seen sections soldered together using very small lengths (1") of bare solid wire as "jumpers". This would be faster and better for changes, connecting power to blocks, etc, but visable. I'm leaning with that or maybe jumpered from the bottom side with longer lengths that would be hidden from view.
The third method I thought of was a buss type with a separate feeder to each section but that might hurt DCS signal and would be as much work as the jumpers above. I could solder wires to each slide connector from the buss.
Any ideas of what's best here for me? I have not tried soldering this track yet. Joe

If you use the jumpers, I suggest putting a loop or double bend to allow some flexibility, to avoid crakcing soldered joints under usage.

I would say that it's not normal to loose power in just 6 sections of track.

I divided the layout into four sections and I moved the power source to two semi equal distance points. I soldered on the feeders at each side of the new blocks about 10" apart. This means I'm feeding each section from one end. I put a bulb at the farthest end and I have one right at the tiu output. I tested an engine and got solid tens. I removed the bulb from the farthest end and still got tens. I ran the engine onto a new section #2 that I had only soldered the first two joiners and still ran perfect and got tens. I'll do more testing, solder the rest of rail joints and retest with rolling stock and more engines but things are now looking good. Must have been a couple of loose rail joints and moved feed from the center of block to the end that was where it was bad. Joe
