The works outing arriving initially in Scottish town (5)
I believe the answer is:
alloa
'scottish town' is the definition.
(Alloa is a town in Scotland)
'the works outing arriving initially' is the wordplay.
'the works' becomes 'all' ('the works' means everything available).
'initially' suggests taking the first letters.
The first letters of 'outing arriving' is 'oa'.
'all'+'oa'='ALLOA'
'in' is the link.
(Other definitions for alloa that I've seen before include "Town built" , "place in Scotland" , "Central Scottish town" , "Athletic club" , "Town on Firth of Forth" .)
