Railway employees drag us off (6)
I believe the answer is:
guards
'railway employees' is the definition.
The definition and answer can be both people as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'drag us off' is the wordplay.
'off' is an anagram indicator.
'drag'+'us'='dragus'
'dragus' with letters rearranged 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" .)
