'job as american rail coordinator' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?

'met leader' is the wordplay.
'met' becomes 'Yard' (Scotland Yard, Metropolitan Police HQ).
'leader' becomes 'master' (master is a kind of leader).
'yard'+'master'='YARDMASTER'

'for' acts as a link.

Can you help me to learn more?
