Rail transport from Turkey packing in sheep roughly (7)
I believe the answer is:
tramcar
'rail transport' is the definition.
'tramcar' can be an answer for 'transport' (tramcar is a kind of transport). I am unsure of the 'rail' bit.
'turkey packing in sheep roughly' is the wordplay.
'turkey' becomes 'tr' (abbreviation eg in internet addresses).
'packing' indicates putting letters inside.
'in sheep' becomes 'amr' (I can't justify this - if you can you should give a lot more credence to this answer).
'roughly' becomes 'ca' (abbreviation for circa).
'amr' enclosing 'ca' is 'amcar'.
'tr'+'amcar'='TRAMCAR'
'from' is the link.
Can you help me to learn more?
(Other definitions for tramcar that I've seen before include "Passenger vehicle running on rails" , "Electric transport" , "Electrical vehicle" , "Public street transport on rails" , "Electrically driven public transport vehicle" .)
