Oddball taking Charlie to the station (5)
I believe the answer is:
crank
'oddball' is the definition.
(crank is a kind of oddball)
'charlie to the station' is the wordplay.
'charlie' becomes 'C' (phonetic alphabet: alpha, bravo, charlie etc.).
'to the station' becomes 'rank' (I've seen this in another clue).
'c'+'rank'='CRANK'
'taking' is the link.
(Other definitions for crank that I've seen before include "Person with strange and often aggressive ideas" , "Eccentric - starting handle" , "Turn a handle - weirdo" , "Person with strange ideas, or machine part" , "Wind (up) - oddball" .)
