Railway switch consists of a switch, connecting rails and a frog. Connecting rail set of an ordinary switch consists of two straight and curved rails. Curved rails have some radius. This curve is called a switch curve.
In railML3 model it is possible to represent radius of each branch of the railway switch. Negative and positive values have corresponding meaning defined as in the <horizontalCurve>/@radius attribute.
| Case | leftBranch/@radius | rightBranch/@radius |
|---|---|---|
| Ordinary switch a) | 0 | -300 |
| Ordinary switch b) | 0 | -300 |
| Ordinary switch c) | 300 | 0 |
| Ordinary switch d) | 300 | 0 |
| Inside curved switch a) | -300 | -280 |
| Inside curved switch b) | -300 | -280 |
| Outside curved switch | 300 | -300 |
