Was playing around with a track mod and wanted a custom speed of 20km/h to look like the built-in medium speed track with the brown (wooden sleeper ?) 'look'. Thought the following would do the trick but it displays as the grey high-speed (concrete sleeper ?) 'look'.

It appears correctly in the track building dialogue box but not on the actual map.

Would appreciate if someone would point out the obvious mistake - thanks.
