NO! Don't take out the factory in the background--that's what made the final image come together!
The last image-showing the side of the train is great. In art we often want a foreground, mid ground, and background in our compositions. These add interest when the elements are composed properly.
That image works because the train--not very interesting by itself--is now offset to the left and you have the lead-in lines of the other train tracks on the right--as foreground--then you have that great factory structure in the background as a secondary center of interest.
Nice job! Jerry V.
