New in Rail Workflows

Learn about enhancements to rail workflows.

New in 2025.2

• To facilitate the work of rail designers in the UK and France and meet their design standards, Grade/Slope in Ambient Settings now has (run) and (mm per m, mm/m) formats for cant gradient parameters in the Cant Tabular Editor.

  For more information, see Ambient Settings Tab (Drawing Settings Dialog Box).

• Added new cant parameters for Civil 3D labels. See Layout Tab (Label Style Composer Dialog Box) for more information on editing label components.

• Added new cant parameters for horizontal alignment in the Cant Tabular Editor for cant calculations. This provides an overview of the necessary parameters in rail design related to such calculations.
  • Cant Jerk (m/s^3 or ft/s^3)
  • Cant Ratio

  For more information, see Cant Tabular Editor Dialog Box.

• Added API support for the Cant Jerk and Cant Ratio parameters.
• Extended support for the Cant parameters in the RailCANTInfo structure API.
• Added the CheckTurnoutCatalog command to check the syntax or configuration errors in turnout standard files. For more information on turnout commands, see Turnout Command Reference.

New in 2025.1

• Added new cant parameters for horizontal alignment in the Cant Tabular Editor for cant calculations. This provides an overview of necessary parameters in rail design related to such calculations:
  • Curve Radius
  • Equilibrium Cant Gradient
  • Equilibrium Cant Vertical Speed
  • Cant Deficiency Gradient
  • Design Speed
  • Cant Deficiency Vertical Speed
  

  For more information, see Cant Tabular Editor.

• Modified the side parameter for turnouts to help improve rail design documentation.
  • In the Create Turnout dialog box, the Side parameter has been changed to Alignment Side for clarity.
  • A Turnout Side property is available in the Object Properties palette and Text Component Editor of the turnout Label Style Composer.

For more information, see Content Tab (Create Turnout Dialog Box).

Added support for creating spirals in turnout diverted alignments. Optimization includes:

• Simple spiral by length/radius.
• Simple spiral by pass through point.
• Compound spirals.
