If the car does not take the diverging route when the points are thrown for the diverging route the problem almost is certainly with the turnout. This must be especially true if you are using the same forty foot boxcar for all your tests.

The fact is does not derail has me a bit confused. The points must be so far off that it does not pick the flange for route direction, and the outer wheels do not end up in between the point and stock rails on the diverging side.
Weird, to say the least.

Living the dream.
Interesting problem. I put a #6 Code 83 Atlas Snap track turnout on my layout. Whenever I get a section built I hand roll a 40' boxcar along the section to make sure the rails align and there are no surprises. Well, I found one.
When going from the point rails towards the frog the car continues along the straight section and doesn't go onto the turnout section. Holding the throwbar actuator tightly makes no difference. The car does NOT derail.
So, is the problem because
1) The car is too light? I need to add 1.5 oz to meet RP20.1;
2) Is the track out of gauge?
3) does it need an electric throw enging to hold the critter in place?
Thank you.
