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 quite 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. Import Dutch railway milestone data from ProRail in accordance with the prescribed procedures

2. Import Dutch signal locations from ProRail, also in accordance with the prescribed procedures

3. Find a way to merge ProRail's rail geometry and tagging data with OSM data


All Dutch stations now have their respective references, which are rendered in ORM.

All Dutch railway lines now have their line speed limits. These are specific per railway line and not per railway track (a railway line can consist of multiple tracks). The next step is to map the speed limits per track. Data from ProRail is available to make this possible. I rendered the data in QGIS, in accordance with the ORM speed layer legend. 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 (and was generated by QGIS).
