Your photographs are really good. Here's my suggestion as of avoiding trouble with train operators. Try not to take a photo of the ends of the train cars too often when the train operator is controlling the trains. Generally, train operators usually don't mind having their picture taken, but keep this in mind, some may not like to be recorded operating train cars. If you have to take a photo of the ends of the trains, take the photo of the last car more often, therefore you wouldn't have to face the issue with the T/O's. That's just my suggestion.
