Our main club test track has 5 OO gauge tracks and one P4 gauge track. It is set up at least once a month, and many members bring stock to run on it. We also have an N Gauge test track (front of picture) which is out most weeks. We are currently building an O gauge test track.
There is a 3 foot long multi-gauge track permanently set up in the club room to test locos and check they run smoothly. In addition we have rolling roads for most gauges for running in locos.
