Most 3 Rail O Gauge track is sectional, meaning that the pieces are rigidly constructed in a certain length or curve diameter. All types of track are made in a variety of curve diameters, and all lines offer a variety of switches [the track sections that allow two tracks to diverge or merge together] and crossing sections. Some manufacturers also offer flexible track sections, which can be bent to a variety of curvatures.
However, the different types of track normally do not hook together without the use of adapter tracks. The differences are due to the level of detail the track has and its method of construction. In the late 2000s, there are seven major types of O Gauge track on the market.
