Run through train (8)

I believe the answer is:

rehearse

I believe this is a double definition.

'run through' is the first definition.
(I've seen this before)

'train' is the second definition.
(I've seen this before)

(Other definitions for rehearse that I've seen before include "Practice in theatre" , "Go over" , "prepare for performance" , "Practise like actor" , "Prepare for a stage production" .)

I've seen this clue in The Telegraph.
