New to "O" scale and would like to know what the difference is between items described as "Scale", "Semi Scale" and others with no scale reference and why?

Thanks, GovB
Happy Rails to You, GovB

Some companies make stuff to a scale of 1:48, which is closer to true scale for O gauge, other companies make stuff between 1:43 and 1:54 scale or off scale. 
Semi scale(usually means below scale) and can have different meanings with different companies.
Some of the larger offerings like the UP big boy(6-8-8-6) and the articulated steam or tri-plex are closer to 1:52 scale to make the engine run on O gauge track. If you had the UP big boy at scale it would need about 096 curves to operate.

I hope this helps.
