What to pay to get a single school meal? (5,4)

Ross

I believe the answer is:

train fare

'what to pay to get a single' is the definition.
(single train fare)

'school meal?' is the wordplay.
'school' becomes 'train' (training is a kind of schooling).
'meal?' becomes 'fare' (I've seen this before).
'train'+'fare'='TRAIN FARE'

(Other definitions for train fare that I've seen before include "Perhaps commute cost" , "the cost of going" .)

I've seen this clue in The Times.
