Rail Head Treatment Train Components

My version of the RHTT. Not to scale, as just taken from photographs. I am happy if it just looks ok and doesn't need to be accurate to the last millimetre.

Feel free to change anything to make it the way you want.

The two wagons that I designed it on are just flat topped and will give a representation only and not a true prototype.

Please be aware that it will not fit on the Dapol spine wagon, as I do not know the dimensions. I hope to purchase a pair of spine wagons soon and will redesign the model to fit.
