model in HO and am having an issue with my Peco curved turnout. I seem to get frequent derailments when switching to the inner passing track. I am thinking of switching out that Peco for a Atlas Mark 3 curved turnout or should I make a major change and reposition the turnout on a straight? I have to say I am a little disappointed with Peco as I also tend to have some derailment issues in another area ( just a straight turnout) especially when running a steam locomotive where the front wheels will tend to go off. Peco switches are cheap and I thought the extra $ spent would pay off. Doesn't look to be the case.
