Passion and argument about opening of historic transport hub (8)

I believe the answer is:

heathrow

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

'transport hub' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'passion and argument about opening of historic' is the wordplay.
'passion' becomes 'heat' (synonyms).
'and' says to put letters next to each other.
'argument' becomes 'row' (to row is to argue).
'about' is a charade indicator (letters next to each other).
'opening of' suggests taking the first letters.
The initial letter of 'historic' is 'h'.
'row' after 'h' is 'hrow'.
'heat' put next to 'hrow' is 'HEATHROW'.

Can you help me to learn more?
