Kilometre markers on the railway network

Geographical position of the kilometre markers along the tracks with the id and the name of the mark as it can be read on site. Kilometre markers help train drivers to locate themselves on a railway line.

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.

Combination of kilometre markers and main tracks: indicates for which main track (and line) the kilometre marker is applicable.

Important note:
These data are managed according to the Lambert72 coordinate system (EPSG 31370) and give the track alignment with an accuracy of 10 cm to 1m depending on the location. In order to make a map display on this site, the data has been converted to WGS84. This results in a small loss of accuracy.In the "Export" tab you can download both the file following the Lambert72 system (in GeoJSON) and the file in WGS84.

本数据集收录了轨道沿线里程标（kilometre markers）的地理位置信息，包含可在现场读取的里程标编号与名称。里程标可辅助列车司机在铁路线路上确定自身位置。

本数据集可与以下数据集关联：
1. 主轨道列表及地理位置：Infrabel铁路网中带有线路编号的主轨道地理定位线路（例如L161）。
2. 全轨道区段地理位置：Infrabel铁路网内全部轨道区段的线路信息，而非仅覆盖主轨道。
3. 里程标与主轨道关联表：明确该里程标适用的主轨道（及对应线路）。

重要说明：
本数据集采用Lambert72坐标系（EPSG 31370）进行管理，轨道线形的定位精度依点位不同可达10厘米至1米。为实现本网站的地图展示需求，数据已转换为WGS84坐标系，此转换会带来小幅精度损失。在"导出（Export）"标签页中，您可下载采用Lambert72坐标系的GeoJSON格式文件，以及WGS84坐标系格式的文件。
