Combination of kilometre markers and main tracks

This dataset indicates for each kilometre marker for which main track (on a railway line) the kilometre marker applies.
A kilometre marker can apply to several main tracks, even from different lines.A kilometre marker is not always valid for the nearest or all nearby tracks.

This dataset can be linked to :

List and geographical position of the main tracks: Geolocalised route of the main tracks with a line number on the Infrabel network (e.g. L161).

Geographical position of all track segments: route of all track segments on the Infrabel network, not only the main tracks.
Kilometre markers on the network: positions of the kilometre markers located along the tracks.

本数据集明确了铁路线路各公里标所对应的正线（main track）。单个公里标可对应多条正线，甚至可跨不同线路；且公里标并非始终适用于其邻近的最近线路或全部邻近线路。

本数据集可与以下数据关联：
1. 正线列表及地理定位数据：Infrabel铁路网内标注线路编号（如L161）的正线地理定位线路数据；
2. 全轨道区段地理位置数据：Infrabel铁路网内所有轨道区段（不限于正线）的线路数据；
3. 网络内公里标数据：沿线路布设的公里标位置信息。
