Railroad employee
I believe the answer is:
porter
'railroad employee' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for porter that I've seen before include "One carries luggage" , "Doorkeeper; dark beer" , "Baggage-handler" , "One fetches and carries the drink" , "Railway worker; the Ruler of the Queen's Navee (G&S)" .)
