Steam Drum
Steam drum is part of the boiler in a coal fired power plant. It is located at the top, steam collects there on its route to the turbine. The model of the steam chest was made to be modular, so that loads of different lengths could be made to fit either a single flatcar or two flatcars. Here is very good video on how a coal fired boiler works with all of the components, and where the steam drum is located.

Heat Exchanger
The prototype of this load is made by Air Products. This 3D printed load is made by Focus Architecture. Focus Architecture provides all the customizable parts, you add your own PVC pipe. This enables the adjustment of the lengths of the loads to fit the flatcars.
