Finally, an easy way to place narrow gauge double track!
The default track used is Prowler901's Narrow Gauge Track (kuid 43955:38000), but you can change the track used to your favorite narrow gauge track if you like.
This is an alias of Auran's '2 track wood' in order to get the preview in the Surveyor track menu. The track spacing is set to 2.5 meters to maintain compatibility with the default signals.
