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 straight reroutes. Also, how to apply joiners when trying to repair different sections. Was careful on alignment and gluing 1st time, but apparently not good enough to not need to take apart.
