The track is split up into the following smaller interacting parts:
| Segment | 1 Track, 2 Contacts, 1 Signal |
|---|---|
| Segment_bid (bi-directional) | 1 Track, 2 Contacts, 2 Signals |
| Track | 1 Track |
| Track_bid | 1 Track |
| Point_in | 1 Point with 2 incoming and 1 outgoing tracks |
| Point_out | 1 Point with 1 incoming and 2 outgoing tracks |
| Point_bid | 1 Point, 2 to 1 bi-directional point |
| Cross_in | 1 Track, 2 Points, has 2 incoming, 1 outgoing and 1 bi-directional track where incoming trains get on the main track and outgoing come from the side track |
| Cross_out | 1 Track, 2 Points, has 1 incoming, 2 outgoing and 1 bi-directional track where outgoing trains come from the main track and incoming go to the side track |
The differentiation of bi-directional and uni-directional Elements is made to have simpler parts for the unidirectional parts.
