Engineers more recent track studies (9,6)

I believe the answer is:

refresher course

'studies' is the definition.

'engineers more recent track' is the wordplay.
'engineers' becomes 're' (Royal Engineers).
'more recent' becomes 'fresher'.
'track' becomes 'course' ('course' can be a synonym of 'track'**).
're'+'fresher'+'course'='REFRESHER COURSE'

(Other definitions for refresher course that I've seen before include "Training" , "sweet group?" , "it helps you get up to speed" , "further education?" , "study update" .)

I've seen this clue in The Telegraph.
