As usual, a first class modeling job, my friend! That's an interesting structure, designed for a cold climate, I guess?
I have two questions, Robin:
A prototype question: How did they heat those tanks - was there a crew of some sorts living in or near these tanks to put some more coal or wood into the stove? Or was this the job of the passing locomotive crews?
And a question about your modeling: How did you model the water spout? It looks great!
