This locomotive was regularly rostered to Royal Train duties when members of the Royal Family were travelling to, or returning from the Sandringham Estate located on the branch line from Kings Lynn to the coastal terminus at Hunstanton.
The customary van, probably for perishables, an often leading such passenger workings such as this , is coupled next to the engine."
