Holiday on popular train (5,2)

Ross

I believe the answer is:

break in

'train' is the definition.
(thesaurus)

'holiday on popular' is the wordplay.
'holiday' becomes 'break' (I've seen this before).
'on' is a charade indicator (letters next to each other).
'popular' becomes 'in'.
'break'+'in'='BREAK-IN'

(Other definitions for break in that I've seen before include "Illegally enter" , "Enter forcibly" , "Forced entry" , "Interrupt - burglary" , "Criminal entry" .)

I've seen this clue in The Independent.
