Trying to give a little constructive criticism here.
Whole train pictures are tough. You're doing a good job with exposure and the rule of thirds, but details in the foreground can make or break a picture. I take most of my pictures with an extra wide angle lens, and have a bunch that I would gladly like to be able to retake because I missed seeing objects in the foreground.
The first shot, #200097, could be improved by being taken from a higher elevation. Taken from ground level, the emphasis is on the grass. The old rectangle with your fingers works better than the viewfinder for visualizing the picture.
Next #200100. 484 is just a tad close to edge of the frame. Also, I probably would have broken of the weed that is obscuring the second driver.
#200103. From a railnut aspect, all I can see wrong is the lack of smoke from 484. Next time buy the fireman a better brand of beer.
As a photographer in general, I like it.
#200106. Two things distract me, the road and the fence. The fence can be cropped out.
#200112. Again, more beer for the fireman. You have enough elevation that the fence and grass is not a distraction. Another keeper!
#200118. Going thru the curves works great for entire train shots. A little tight on cropping on the left. Moving to the left could have gotten the entire train in the shot. But it also leaves the viewer wondering what is missing, adds a little mystery. And buy the section gang a round so the ties aren't there.
Like I said, you really have to watch the details in the foreground. Use your hands to frame the shot. With your proximity to the locations, take your time and scout out the locations. And keep taking pictures, it's the best way to learn. I'm really enjoying the pictures.
Once you get used to seeing the details in the foreground, you can learn how to incorporate them in the picture. You can use them to force the viewer to a point, or make other objects blend into the picture.
