Santiago: Just a minor suggestion: on your water column, the spout should be flush with the retaining bracket. The spout was counterbalanced, and would "naturally" return to that position. Photos of locomotives taking on water, the fireman is holding the spout down with his foot.
Very satisfying photos! Your train is reminiscent of the Burlington (IA)-Chicago local that made all stops in between. There is a photo of it in the BRHS Hudson publication - much head-end eqpt., the original pattern dome car, and a rider coach tacked on at Aurora. Photo was taken in Downers Grove in 1949, pulled by 4-6-4 #4003.
