Charcoal cooler used in the old cylindrical retort plants. The charcoal was 

 shovelled from the retorts directly into this container and kept in an air-tight 

 condition to prevent combustion. In the modern plant the charcoal is now 

 cooled in the same truck in which it is heated, the trucks being run into cooling 

 ovens on standard gauge tracks.
