Limit transport for internees (9)

Ross

I believe the answer is:

constrain

I'm a little stuck... Click here to teach me more about this clue!

'limit' is the definition.
(I know that constrain is a more specific form of the action limit)

'transport for internees' is the wordplay.
I cannot really see how this works, but
'transport' could be 'train' (train is a kind of transport) and 'train' is found in the answer.
The remaining letters 'cons' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for constrain that I've seen before include "Hold back - non-racist (anag)" , "Compel; constrict" , "Restrict scope of (an activity)" , "Compel towards a course of action" , "Restrict the extent of" .)

I've seen this clue in The Guardian.
