A model layout can be whatever the modeller wants - based on actual or imaginary (freelance) railroads.
Prototypical layouts are modelled based on the actual real world railroad. It has to be as close as possible to reality. Freelance modellers have more freedom - but they still need to choose an era so things match, have a purpose for the railroad (e.g. mining, logging) and be similar to prototype practices.
These scenes are part of a module group - every scene different and fun - so it seemed like an imaginary railroad. I didn't check whether that was the fact, though, as I was busy taking pictures.
