There’s a small engine behind the prop train in this shot which pushes the locomotive forward. Removing it required replacing the horse that runs behind it. I grabbed a time-offset translated version of horse for the replacement.
We had a number of photographs and plates of tents and people which we used to extend the town both on screen left and right.
At this point in the story, they crew building the railway should not have reached the mountain range we see in the distance. I translated the the sky down below the horizon to remove them.
Lastly, an artist generated particle smoke for the train. A live smoke element was used in other areas of the shot.
