I've often read that BR fish traffic ceased at the end of the 1960s and this certainly seems to be the case for the Aberdeen and West Highland flows, but I've seen plenty of photos from the 1970s showing fish vans marshalled between the loco and passenger coaches on the Kyle, Far North and Highland Mainline. Were these vans carrying fish and where were they heading? They were universally filthy by this stage! I'd be interested to know the details if anyone can help.
