As shown in the picture below, my calibrated route deviates from the original route. It only happens in very few places, and I have no clue why this happens.

Anyone an idea?

The problem is solved, there were some points along the route with the same M-Value. ArcGIS completely skips those points for calibration, and deviates from the original line.

The solution was to remove the point with identical M-values and recalibrate.

So it was a curve with real dense points and no Bezier curve.

Are you using calibration points, and if so, are there any points missing for the mis-shapen portion?

Is the curve in the original route densified points or a bezier curve?  I would expect the bezier curve to cause issues and not be preserved by the route tools.  I have similar problems with the Locate Features Along Routes tool when I try to overlay line features on to a route built from bezier curves originally.
