Did the Sandringham line for example have freight in living memory?
It did in my living memory
My 1963 WTT shows a goods Mon,Tue,Wed,Fri to Middle Brighton and return, spending from 12:50pm to 3:29pm at Middle Brighton.
Presumably worked by an E class. The Weston Langford Suburban Pt 1 book shows electrified goods yards at Windsor and Elsternwick, goods sheds at Brighton Beach and Sandringham, and a coal siding 1/4 mile past Middle Brighton.
Next line along, there were electrified goods yards/sidings at Glenhuntly, Mentone, Mordialloc, Chelsea, Carrum and Frankston.
Also electrified goods sidings at Hawthorn, Kew, Camberwell, Surrey Hills, Blackburn, Mitcham, Ringwood, Croydon, Mooroolbark, Lilydale, Bayswater and Upper FT Gully.
