Gauge:
Sn3
Other Material:
metal
Notes:
The NASG carries the official NMRA Sn3 Standards Gauge for S-scale 3-foot narrow-gauge track. This gauge can check the track gauge (including turnouts), the equipment's wheel gauge, and the required clearance for items surrounding the track. These three can be combined, because there was only one era during which narrow-gauge was active.
