Would it have been possible to press more to your right and angle the camera more to the left to get a bit more of the QB's structural elements while still getting a good view of the train?
Thanks for your comments! You may be right about the composition, though it'd be easier to get more bridge with a 35mm instead of the 50mm used here. I tend to crop/compose tight and sometimes don't leave enough breathing space for the subjects.
