Railway employees drag us off (6)
I believe the answer is:
guards
'railway employees' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps there's a link between them I don't understand?
'drag us off' is the wordplay.
'off' indicates an anagram.
'drag'+'us'='dragus'
'dragus' anagrammed gives 'GUARDS'.
Can you help me to learn more?
(Other definitions for guards that I've seen before include "Keeps watch" , "They protect" , "Defends" , "Sentries" , "They keep watch" .)
