Hello and welcome to my profile page. My name is Jeroen Wegdam and I study Railway Engineering at Delft university of technology. From that background, I contribute to OpenRailwayMap. I also did some detailling at the Dutch high speed rail infrastructure and in my hometown: the Dutch city of Enschede.


To Do list

In this section, a description of mapping goals for the Dutch ORM, which excludes proposals for new ORM functionalities. The functionality proposals can be found at ORM's github page. The mapping goals are ordered by priority.

  1. Insert the shapefiles that were distributed by ProRail (the Dutch rail infrastructure owner)
  2. Tag all imported railway shapes with their line code
  3. Import Dutch railway milestone data from ProRail (in accordance with the prescribed procedures)
  4. Correctly map all turnouts (points) along with their type (simple, single slip, double slip, etc.) and perhaps their reference number
  5. Import Dutch signal locations from ProRail, also (in accordance with the prescribed procedures)


All Dutch stations have their respective reference codes, which are rendered in ORM.

Since the 7th of April 2015, all Dutch railway lines contain at least their line speed limits. These are specific per railway line and not per railway track (a railway line can consist of multiple tracks).

The ProRail data however, allows for the best possible overview of speed limits. This is gradually being inserted, for it requires a lot of work to merge the data with the OSM data which was already present. At the moment of this profile update (13-08-2017) the majority of the provinces has the improved data implemented. This holds for the provinces of Friesland, Groningen, Drenthe, Overijssel, Flevoland, Gelderland, Urecht and Southern Holland. To allow for a sneak peek into the future, I rendered the shapefiles in QGIS in accordance with the ORM speed layer legend. It shows how the final result of importing all ProRail shapefiles would look like. Please contact me if you'd like me to send you the QGIS file (the data is open to the public).

In the images below, it is shown how the speed layer was before the addition of the line speed limits. The middle image shows the situation as of the 7th of april 2015. The third image shows the future situation.
