Indicates they miss most of the stops (9)

I believe the answer is:
expresses
'stops' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps there's an association between them I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for expresses that I've seen before include "Trains" , "voices" , "'Conveys, articulates (9)'" , "States" .)
