I'm having a problem with two turnouts, both of which are Atlas #6 remotes. Basically, whenever a locomotive or a boxcar passes through the points, the rear truck derails. Using the above photo as reference, If I run a boxcar in the direction of the red arrow, the first truck will go through the points normally and take the diverging track. The first truck runs smoothly, no bumps. But when the second truck goes through, the lead wheel/flange hits the point (indicated by the red arrow) and continues through into the straight track, causing a derailment. I have recently ballasted this track, but I can't remember if the cars went through smoothly before (this is my first layout, and I may have made the mistake of not checking properly if the cars ran through this particular turnout before ballasting - oops). Out of the four turnouts I've ballasted so far, two run very smoothly without any problems, and two have this problem (though this one is by far the worse). The other problem turnout I've cleaned up and seems "better" now. All are Atlas #6 remotes. Looking through a magnifying visor, I've made sure there are absolutely no grains of ballast preventing the closing of the point, but that point is somewhat loose and just does not want to close quite right. Should I take out the dremel the grind down the point until smooth with the rail (i.e. a thinner point)? Any other ways to fix this without having to rip out the turnout and start over?
