Here’s a picture that was taken at the same time as this one.
The light of the setting sun informs whilst simultaneously strengthening the idea that the train is on a journey that has been set before it, not allowing it to do much more than follow a guide, yet still it does so without complaint, blah blah blah.
I like how the light is cast in this shot and that it, combined with the cloud cover, make the image gorgeous (I think).
I also like how the train is slightly blurred, showing it in motion as it stretches off into the distance.
Anyway, I hope you enjoy.
