+## I want to visualize a new track class on the map
+
+Edit the file [`features/track_class.yaml`](https://github.com/hiddewie/OpenRailwayMap-vector/edit/master/features/track_class.yaml).
+
+The file contains a list of track classes, each with a value (the value of the `railway:track_class` tag) and a color.
+
+Add a new entry at a certain place in the list. The value is the `railway:track_class` tag value. For example:
+```yaml
+track_classes:
+  - { value: 'Z', color: 'blue' }
+    # ...
+```
