I bought a new Williams Girls Train O set at York for my wife and set it up on Atlas track for Christmas.  The Steamer on 048 track on the curved sections appears to bang into every outside track connector with the driver flanges and nearly jumps the track.   I am not sure what's wrong ........... but it doesn't like turning on that track.   Never seen anything like it before ........... any advice here would be appreciated like it should only run on tubular track, flange is to big for this track height,  loco wheel spread is not in spec for this track ........ return to Williams, or    Wife is disappointed with her new train set.   Help Santa?
