Spectacular photography! It was a joy to see the B&O Museum in Baltimore after the rebuilding of the roof of the roundhouse exhibition area. Obviously they also did a lot of work on the equipment in it. I'm going to have to get myself down there to visit it again.
I like the diversity of your subjects. Old equipment and old places interest me also but I hungered for more information about some of the things you photographed. That's a problem I have with pictures--I always want to know about what is in the photograph and I'm never content with just viewing the image. I guess that's the difference between photography for its esthetic effect and as part of a process of conveying information. Nevertheless, your photographs are both esthetic and often composed to tell the viewer a lot about the object. I appreciate that!
