The second photo of the Rangierbahnhof Spreitenbach (switch yard/ marshalling yard). This time in black & white and the photo was taken in the opposite direction.
It's an HDR of 5 exposures which was processed with Photomatix. I did the black & white conversion afterwards in Affinity Photo using the Nik Silver Efex plugin.
I shot at f 8 because I wanted to get at least a bit of a star effect in the artificial lighting.
