Understanding Cant

Product Documentation

View Original

Cant is the change in elevation of rails in the horizontal curves in a railway.

Cant is the rail equivalent of superelevation in roads. The tools to calculate cant and superelevation are very similar. For more information, see Superelevation.

Cant Workflow

Note

Cant should be calculated before the corridor model is built along the alignment. The corridor model is not dynamic to changes in the alignment cant data. You must rebuild the corridor to include the updated cant data.
