With the break up of BR we are now used to seeing private liveried loco's and rolling stock on our railways. Not so many years ago a number of companies had their own locomotives used mostly in private shunting yards or factories. These were of various designs and locomotive power, the National Coal Board not surprisingly used coal but others like steel works used battery-electric some had petrol or diesel engines but one that was of interest to me was one I saw standing in the sheds @ Ruddington.
It was in the blue of 'Boots the chemists' and basically had a reservoir of steam in the place of the boiler which had to be 'recharged' each morning prior to work.
I know Hornby and other manufacturers produce rolling stock associated with various companies / products like Polo mints ( there's one on Ebay with a bid of over =A315 ?), BP Oil, Texaco, Bestwood iron works, Norstand Limited Fish Docks ( one of my son's favourites ) or Coca Cola ..... but what about loco's ?
