Similar to 24 down on English school buses (7)
I believe the answer is:
coaches
'buses' is the definition.
('coach' can be a synonym of 'bus')
'similar to 24 down on english school' is the wordplay.
'similar' becomes 'ache' (I've seen this before).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'o4 down on english' becomes 'co' (I am not sure about this - if you are sure you should believe this answer much more).
'school' becomes 's'.
'ache' put after 'co' is 'coache'.
'coache'+'s'='COACHES'
Can you help me to learn more?
(Other definitions for coaches that I've seen before include "People carriers and trainers" , "Trainers or buses" , "Trains" , "Buses, carriages" , "Instructors in sports" .)
