Same trouble with underground (5)
I believe the answer is:
metro
'underground' is the definition.
(synonyms)
'same trouble with' is the wordplay.
'with' indicates a hidden word.
'METRO' is hidden within 'same trouble'.
(Other definitions for metro that I've seen before include "Parisian underground system" , "French underground" , "Parisian underground railway" , "Parisian rail system" , "The underground railway system in Paris" .)
