These wagons are standard Hornby and the only modifications are the painted wheels and my coupling mods. The spills on the tanks are ‘watercolour pencil’, not white, but light grey. These are great for trial and error, if you don’t like it, wipe it of with a damp rag!
After photo research I realised most were quite dirty by the end of the 60’s. I did find attempts at some ‘token cleaning’ so I replicated that on one wagon. This is a rake of eight wagons.
This rake is more akin to the Western Region I believe. My only recollection of milk trains in my area of East Anglia was a very dirty J15 with a couple of full brakes and one or two tanks.
