One accompanying touring team on trailer (5)
I believe the answer is:
wagon
'trailer' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'one accompanying touring team on' is the wordplay.
'one accompanying touring team' becomes 'wag' (I can't justify this - if you can you should believe this answer much more).
'wag'+'on'='WAGON'
Can you help me to learn more?
(Other definitions for wagon that I've seen before include "Vehicle carrying goods" , "Cart; rail truck" , "Transport" , "Van, lorry" , "Railway freight vehicle" .)
