Japanese train in news report (8)
I believe the answer is:
bulletin
'news report' is the definition.
(bulletin is a kind of news report)
'japanese train in' is the wordplay.
'japanese train' becomes 'bullet' (I am not sure about this - if you are sure you should believe this answer much more).
'bullet'+'in'='BULLETIN'
Can you help me to learn more?
(Other definitions for bulletin that I've seen before include "Regular report" , "Brief report issued to the public" , "Newsletter, report" , "Short statement on the news as it happens" , "Short and regular up-date" .)
