BR(S) Southampton Docks to London headcodes

[Fettster42]

I'm still struggling to get my head round SR/BR(S) headcodes. Ones based on type of train were so much simpler. 

What would be the headcodes fir a train of banana wagons going from Southampton Docks to London. Or any goods to/from docks to London. 

[Wickham Green too]

Southampton Docks and Nine Elms, via main line (market goods, fruit or potato train) : single lamp/disc over left hand buffer ( as seen head-on )

Waterloo or Nine Elms and Southampton Docks via East Putney : lamp/disc over left hand buffer ( as seen head-on ) and lamp/disc at centre of buffer beam

 

..... simple !
