Don't quite understand what you mean

sorry sleepers @@Harley966

i thought the sun might melt the sleepers or warp it ? like what i mean is it special track brass or anything? also nice set up @@Harley966

@southdownrider2545 The track is peco streamline flexible 100 nickel silver non rust with plastic wood like looking sleepers the only problem is corrosion on the joiners so I soldered a wire across to carry over the power with allows expansion and retraction to accur in different weather conditions hope that answers that question bud

thank you it does @@Harley966
