Dataset description
| Documentation Code | Test Title | Exchange Code | Test Code | Author | Data Owner | Version | Date |
|---|---|---|---|---|---|---|---|
| IFC4.3AbRV_E1b_AL22 | (RFI) Two alignments with cant | E1b (ALRC) | AL22 | Evandro Alfieri | RFI | 1.0 | DD.MM.YYYY |
Model Dataset
This test case utilises the same dataset of the test IFC4.3AbRV_E1_AL22, with the addition of cant data.
| Filename | Description |
|---|---|
| Alignment1_cant | Alignment parameters for cant segments of the Primary Route |
| Alignment2_cant | Alignment parameters for cant segments of the Diverted Route |
Alignment parameters for cant segments
The cant layout of the alignment (both for Alignment 1 and Alignment 2) is described using a CSV file. The column headers match the IFC attributes for IfcAlignmentCantSegment. Refers to the standard's documentation for their description.

NOTE:
- In Italy, only linear transitions are used for cant
- All distances are in meters
- Applied cant: in a cross-section plane, orthogonal to the track axis, it is the difference in height (ht in the picture below) between two points, of the track plane, that have a conventional distance between them of 1500 mm. The cant is always applied to the external rail (the furthest rail from the center or the curve). Cant measure is positive because the external rail of a track is always higher than the internal rail.
