Transport group known for flying tours love dry and wet weather (4,5)
I believe the answer is:
boat train
'known for flying tours love dry and wet weather' is the definition.
I can't judge whether this definition defines the answer.
'transport group' is the wordplay.
'transport' becomes 'boat' (boat is a kind of transport).
'group' becomes 'train' (train is a kind of group).
'boat'+'train'='BOAT-TRAIN'
Can you help me to learn more?
(Other definitions for boat train that I've seen before include "that runs down track to harbour" , "connecting transport" , "One may be heading for a port" , "Transport to/from docks" .)
