thanks for the help. saw a jig tool that squares up the two pieces with a open slot for soldering that i may try. from what i can tell, need to focus mainly on curves and trouble spots, not the whole track.
are the derailments occuring going into the TO's?
or at the points or frogs?
the wheels are misdirected at the points on 1 switch and the frog on another. The six-axle engine does the worst.
is this done before track is laid down, piece by piece as you go, or after gluing/nailing is complete?
is joiner removed?
file only on top and inside edge of rail - correct?
finally question, any hints/tips on soldering n-scale track?
I have trouble optimizing track. Using Atlas sectional track on scenic ridge layout. Straight and Curves are pretty much debugged, but Turnout Switches are causing too many derailments. Trialed using 3 types of n-scale engines, both directions. Turnout next to curve derails. Turnout on...
