Train tours are reorganised (8)
I believe the answer is:
eurostar
'train' is the definition.
(I've seen this before)
'tours are reorganised' is the wordplay.
'reorganised' indicates anagramming the letters.
'tours'+'are'='toursare'
'toursare' with letters rearranged gives 'EUROSTAR'.
(Other definitions for eurostar that I've seen before include "travel service" , "Passenger rail service from London to Paris, etc" , "High-speed rail link between the UK and France" , "International traveller" , "The train from England to France" .)
