You've got a couple of competing items here. The red streaks, obviously not from the train, because of their brightness placement command attention.
At the same time the light above the tree make a play for center stage.
If you were going for a Christmas tree effect, an angle where the light was at the top of the tree would be a little more effective.
Also, since this is and advance rules challenge, I would recommend eliminating the bird, or whatever the object is, above the gap between the two rail cars.
I think this photo might have worked best for me without rail cars and without red streaks.
A long exposure that's quite different from the norm. Not sure what type of camera you're using, but it doesn't give you a high enough res and the pixel distortion is obvious.
you've tried to get too much here, despite the title. I'm having trouble believing the lights are from the train, when I can see lettering at right. the subject tree is lost among the elements except for the moon.
I'm not sure the the train cars and passing lights add to this shot. Maybe without those it would be stronger and more focused. There's just a little too much going on here.
