Within the section on wagons connected with the coal trade not only are Forest collieries dealt with but also the coal factors and merchants and those bringing wagons into the coalfield for loading from places such as Bridgwater and Bristol. Whenever possible a brief history of the wagons' owners has been given to enable modellers and historians to establish dates at which particular wagons could be seen in trains together.

Also included are valuable insights into the business of moving coal, from the colliery, via the local docks or by rail, to the end user.
