I have attached two pictures from Maple Leaf Tracks "Soldier Summit" Route.
In this picture Super Elevation is NOT enabled.

In this picture Super Elevation IS enabled.

Note the large section of track that is missing. This may be due to a double track section, this means, one track shape file with two tracks that are side by side. So the bug might be that in some cases double track sections are not being super elevated properly, and in this case it is clearly the inside track that is not being rendered. There is no log error created when the train runs over this trackless section.
