The LNER Encyclopedia

I remember well the headcodes used on the GE Section of the LNER and in BR(ER) days for passenger trains to show the destinations of the trains. My question is: Were these same headcodes used for freight trains also, as was the case on the Southern and BR(SR)? If not, presumably BR Standard headcodes were used for the freight trains.

As a modeller, I like to get everything right, including locomotive headcodes. I would appreciate anyone who knows for sure providing me with the answer to my question.
