The Coal and Ash Conveyance System and Other Interior Curiousities

 Continuing on I am working out some details, still trying to make the building line up at the elevated coal bunker. I worked on a cross section depicting the crane on it's runway and used the blueprint as best I could to show the office.

I am still not sure how the coal hopper worked, although I have traced the circuit from the delivery bin up the elevator. It did take a jog north on its way after dumping into the boiler area back down a shaft.
