@BenLMaggi posted:What you are showing is a curve in one direction leading into a switch where the diverging track curves in the opposite direction... creating what is known as an "S" curve (because of its shape). This is bad practice in real life and in model form. Is there where the derailments are occurring, when the train takes the diverging route? If so, try putting a piece of straight track between the curve and the switch itself to create a more gentle bend.
No. The diverging route isn't hooked up yet. It is happening on the straight route. When it enters the turnout, the wheel bumps up on the moveable point where it touches the outer rail creating a thicker obstacle for the wheel flange to clear. Instead, the wheel flange hits the double thick point and rides up on it.
