I cant be the only one dealing with these issues of TRS22 treating bridges and track as two separate entities...  I have tried three or four different bridges here all with varying results.  in this attempt, there is nothing I could do to get the track and bridges to line up.  adding a spline point to the track results in an immobile spline point.  Note:  nothing in this picture has "straighten spline" applied.  and applying it, changes nothing.
