Schools Summit at Town Hall, maybe (5,4)

I believe the answer is:

train stop

I'm a little stuck... Click here to teach me more about this clue!

'town hall maybe' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'schools summit' is the wordplay.
'schools' becomes 'trains' (training is a kind of schooling).
'summit' becomes 'top' (synonyms).
'trains'+'top'='TRAIN STOP'

'at' is the link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
