'operated' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'how any properly run railway' is the wordplay.
I cannot really see how this works, but
'properly' could be 'right' (synonyms) and 'right' is present in the answer.
'railway' could be 'line' (line is a kind of railway) and 'line' is located in the answer.
This explanation may well be incorrect...

'is' acts as a link.
