Hi! I have just begun a 4x8 layout using E_Z track and am having issues with cars derailing at turnouts. Seems like the flange on the wheel collides with the end of the points and then slips between the point and the track. I have to say I give Bachmann a big thumbs down on quality control with these turnouts. Any suggestions on how to fix it? The points are riveted in so I can't easily remove thm to taper them.
