School meals leading to transport cost? (5,4)
I believe the answer is:
train fare
'transport cost?' is the definition.
(cost of travelling on a train)
'school meals leading' is the wordplay.
'school' becomes 'train' (training is a kind of schooling).
'meals' becomes 'fare'.
'leading' means one lot of letters go next to another.
'train'+'fare'='TRAIN FARE'
'to' acts as a link.
(Other definitions for train fare that I've seen before include "Perhaps commute cost" , "the cost of going" .)
